So if that corner is split you have to make it equal 90 degrees.
90-31=59 degrees
If you want to find angle CBA you add all the angle you know so far up.
90+59=149 degrees
Triangles have to add up to 180 degree so
180-149= 31 degrees
Answer is 31 degrees
Answer:
59
Step-by-step explanation:
A is a 90 degree angle, we can see the other side is 31
so we subtract 90-31=59

what is 1 +1 pls HELP
Answers
Answer:
2
Step-by-step explanation:
Subject: Re: Need the math proof for 1 + 1 = 2
The proof starts from the Peano Postulates, which define the natural
numbers N. N is the smallest set satisfying these postulates:
P1. 1 is in N.
P2. If x is in N, then its "successor" x' is in N.
P3. There is no x such that x' = 1.
P4. If x isn't 1, then there is a y in N such that y' = x.
P5. If S is a subset of N, 1 is in S, and the implication
(x in S => x' in S) holds, then S = N.
Then you have to define addition recursively:
Def: Let a and b be in N. If b = 1, then define a + b = a'
(using P1 and P2). If b isn't 1, then let c' = b, with c in N
(using P4), and define a + b = (a + c)'.
Then you have to define 2:
Def: 2 = 1'
2 is in N by P1, P2, and the definition of 2.
Theorem: 1 + 1 = 2
Proof: Use the first part of the definition of + with a = b = 1.
Then 1 + 1 = 1' = 2 Q.E.D.
Note: There is an alternate formulation of the Peano Postulates which
replaces 1 with 0 in P1, P3, P4, and P5. Then you have to change the
definition of addition to this:
Def: Let a and b be in N. If b = 0, then define a + b = a.
If b isn't 0, then let c' = b, with c in N, and define
a + b = (a + c)'.
You also have to define 1 = 0', and 2 = 1'. Then the proof of the
Theorem above is a little different:
Proof: Use the second part of the definition of + first:
1 + 1 = (1 + 0)'
Now use the first part of the definition of + on the sum in
parentheses: 1 + 1 = (1)' = 1' = 2 Q.E.D.

A. Write an expression to represent the difference between the two points shown on the number line.
B. Find the distance between the two points. [Hint: Remember that distance is always positive.]
Answers
Part A
distance of point 1 = -1.6
distance of point 2 = 0.3
difference: -1.6 - 0.3 = -1.9
distance: 0.3-(-1.6) = 1.9
The expression that represents the distance between the two points is |0.3 + 1.6| and the distance between the two points is 1.9 units
The expression of the distanceThe points on the line are represented as:
Point 1 = 0.3
Point 2 = -1.6
The distance between the two points is calculated using the following absolute value equation
d = |Point 1 - Point 2|
Substitute the known values
d = |0.3 - -1.6|
This gives
d = |0.3 + 1.6|
Hence, the expression that represents the distance between the two points is |0.3 + 1.6|
Evaluate the expressionIn (a), we have:
d = |0.3 + 1.6|
Evaluate the sum
d = |1.9|
Remove the absolute sign
d = 1.9
Hence, the distance between the two points is 1.9 units

A cheetah can run at its top speed for about 25 seconds. Complete the table to represent a cheetah running at a constant speed. explain your reasoning
Hurry please I need it ASAP!!
Answers
The cheetah must arrive at the same place at the same time:
x = 90t
650 + 60t = 90t
30t = 650
t = 650/30 ≅ 21.7 s
It takes the cheetah a little more than 20 s running at 90 ft/s to reach the moving antelope, so assuming the antelope can maintain its speed of 60, it is safe.
Find the required table attached
Since the speed of the Cheetah is constant, this means that the speed must be the same all through in the table.
To get the unknown time and distance, we will have to use the formula below:
Speed = Distance/Time = kWhen distance = 120m, time = 4secsSpeed = 120/4 = k
Speed = 30m/s = k
We are to get the distance when the time is 25secs
Speed = Distance/Time
30 = d₂/25
d₂ = 30 × 25
d₂ = 750 m
To get the time in the third column
Time = Distance/Speed
t₃ = 270/30
t₃ = 9seconds

The parallel lines are; Lines e and f are parallel because their same side exterior angles are supplementary.
How are parallel straight lines related?Parallel lines have the same slope since the slope is like a measure of steepness and since parallel lines are of the same steepness, thus, are of the same slope.
Since the given parallel line has equation y = 4x + 2, thus its slope is 4 and thus, the slope of the needed line is 4.
We have given that Lines e and f are intersected by lines a and b.
At the intersection of lines a and e, the uppercase right angle is 110 degrees. The lines b and e, the uppercase right angle is 110 degrees. The lines b and f, the bottom right angle is 80 degrees.
