Answer:
x = 30
y = 5
Step-by-step explanation:
Because the top triangle shows 3 congruent angles, we know it's an equilateral.
Therefore 8y = 40
y = 5
______________
Now we have two sides of the triangle: 40 and 80.
The lower left angle of the whole triangle must be 90 degrees because if the hypotenuse is twice the adjacent side, it must be a 30-60-90 triangle.
So, the larger angle containing angle x must be 90 degrees. And because we know that the adjacent angle (equilateral triangle) is 60 degrees, angle x must be 30.

A bag contains 35 red counters only. Chen adds green counters to the bag. The probability of picking a green counter is now 0.3 How many green counters did Chen add?
Answers
Answer:
15
Step-by-step explanation:
Red counters = 35
Number of green counters = x
P(picking a green counter) = 0.3
Probability = required outcome / Total possible outcomes
Required outcome = number of green counter
Total possible outcomes = green counter + red counter
Hence,
0.3 = x / (35+x)
0.3(35 + x) = x
10.5 + 0.3x = x
10.5 = x - 0.3x
10.5 = 0.7x
x = 10.5 / 0.7
= 15
Number of green counters = 15

d. 12(19.95 +2)
Answers
Answer:
Option d 12(19.95 + 2)
Step-by-step explanation:
The answer would be an option d, since we know that she gets paid $19.95 plus the $2 per haircut, and we know that she gave 12 haircuts there for we multiply the sum of $19.95 and $2 by 12, and that can be written down as...
12(19.95 + 2)

Two angles of a triangle measure 55 and 20 what is the measure of the third angle of the triangle
Answers
Answer:
105 degrees
Step-by-step explanation:
well if we take a look at this
we know for sure that every triangle must have a total angle measurement of 180 degrees
so if we take the information we have and we add those together
55 + 20
that will give us
75
then in order to find the missing angle measurement we take the total number of degrees in a triangle and subtract the two angles together from it
180-75
giving us 105 degrees as the third measurement of the angle in the triangle
Answer:
the third measure is [tex]105[/tex]°
Step-by-step explanation:
All measures of a triangle add up to 180°
[tex]A+ B + C = 180[/tex]
[tex]20 + 55 + C = 180[/tex]
[tex]75 + C = 180[/tex]
[tex]C = 105[/tex]°

2/5 x 5/4 in fraction in its simplest form
Answers
Answer:
The answer is 1/2. When you multiply the numerator and denominator, you get 10/20. If you divide the top and bottom by 5, you get 1/2.
The equivalent value of the fraction is A = 1/2 = 0.5
Given data ,
Let the equation be represented as A
Now , the value of A is
Let the first fraction be p
Let the second fraction be q
Now , A = pq
when the value of p = 2/5
And , when the value of q = 5/4
On simplifying the equation , we get
A = ( 2/5 ) ( 5/4 )
So , the left hand side of the equation is equated to the right hand side by the value of ( 2/5 ) ( 5/4 )
A = ( 2/5 ) ( 5/4 )
A = ( 2 x 5 ) / ( 5 x 4 )
On simplifying , we get
A = 10/20
Divide by 10 on the numerator and denominator of the fraction , we get
A = 1/2
A = 0.5
Therefore , the value of A = 1/2 = 0.5
Hence , the fraction is A = 1/2 = 0.5
