Answer:
the angle closest to the 40degree angle is a right angle, so it is 90 degrees. The one with two lines is 50 degrees, and the farthest angle is 40 degrees
Step-by-step explanation:
A square symbol over an angle means it is a right angle, so it will always equal 90 degrees.
The already labeled angle (40 degrees) is equal to the farthest angle.
Once you have two angles, you can find the third angle by simply subracting the two from 180 like this:
180 - 90 - 40 = 50 degrees.

What is mean by Angle?An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.
Given that;
Measure of angle m ∠AXC and m ∠BXC are,
m ∠AXC = 100 deg.
m ∠BXC = 80 deg.
Hence, We get;
m ∠AXC + m ∠BXC
= 100 + 80
= 180 degree
Thus, The correct relationship between the pair of angles m ∠AXC and m ∠BXC are,
A. They are supplementary angles,

Find the area of the following
triangle:
8.5 cm
6 cm
19 cm
A= [?] cm?
pleaseee... need asapp!!!
Answers
EXPLANATION: Find the length of the smaller bottom on the triangle by using pythagorean theorem, then from there you multiply the base x height (6.02 x 6) and then divide by 2. Save that number for later. (18.06) Then subtract the 6.02 from 19 to find the base of the other small triangle. You would get 12.98. Multiply the base and height (12.98 x 6) and divide by 2. You would get 38.94. Then add the two areas together (38.94 + 18.06). The answer would then be 57.
The area of the given triangle will be 57 cm^2
ConceptThe value of altitude and base of triangle is givenWe will just put the value of base of triangle and altitude in formula of area of triangleHow to solve this problem?The steps are as follow:

fill in blanks to write the function when x=3 h(x)=-4-7, when x=3:
h(__)=__
Answers
Answer:
h(x)= -4x-7, when x=3
Answer= h(3)= -19
Step-by-step explanation:
Substitute 3 for x in the function and simplify:
h(x) = -4x – 7
h(3) = -4(3) – 7
= -12 – 7
= -19
The value of the function h(x) = -4x - 7 at x = 3 will be -19.
What is function ?The function is defined as a relation between a set of inputs having one output each.
We have,
h(x) = -4x - 7,
So,
When
x = 3
So,
Substituting x = 3 in the given function,
i.e.
h(x) = -4x - 7
We get,
h(3) = -4 * 3 - 7
h(3) = -12 - 7
So,
h(3) = -19
So, the given function at x = 3 is -19.
Hence, we can say that the value of the function h(x) = -4x - 7 at x = 3 will be -19.

Answer:
u = 21
Step-by-step explanation:
WX = XY because (VW = VY)
WX = u + 42
XY = 3u
u + 42 = 3u
42 = 3u - u
42 = 2u
u = 42 / 2
u = 21
Answer:
u = 21
Step-by-step explanation:
Consider triangle XWV and triange XYV
XV = XV (common)
Angle XVW = Angle XVY (given)
VW = VY (given)
∴triangle XWV ≅ triange XYV (SAS)
∴ XW = XY (corr. sides, ≅ triangles)

Step-by-step explanation:
Given the expression
√(x+2) * √(x-2)
= √(x+2)(x-2)
Expand
= √x(x)-2x+2x-2(2)
= √x^2-4
Hence the product of the expression will give √x^2-4
