EMERGENCY! PLEASE ANSWER ASAP!

y=53

Step-by-step explanation:

the sum of all angles in a triangle is 180 so first you need to figure out what angles you can identify.

by adding 48 and 28 you see that only 76° have been taken so you will subtract 76° from 180 to get 104 now you can start to solve.

1.) a straight angle is equal to 180° so subtract 104 from 180 to get 76 l°

2.) substitute 76° into the equation to get 76=2y-30

3.) work it out

76=2y-30

+30 +30

106=2y

2. 2

53=y

4: check your answer

2(53)-30

106-30= 76

Step-by-step explanation:

28+48=2y-30(sum of two opposite interior angle is equal to the exterior angle)

now

76=2y-30

or , 76+30=2y

or , 106=2y

or , 106/2=y

therefore , y=53 degrees

furthermore , the value of 2y-30

=2*53-30

=106-30

=76

Hope it helps man

b i think

step-by-step explanation:

not really sure

answer: translate the circles so they share a common center point and dilate circle y by a scale factor of 3.
