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

1 1/4 hours

step-by-step explanation:

2/4 + 2/4 + 1/4 = 5/4 or 1 1/4

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x
