I will give brainliest to the correct answer ONLY THE FIRST 2 PROBLEMS

Step-by-step explanation:

7. <4 = 52.7

    <2 = 52.7

  180-52.7 = 127.3 for <1 and <3 vertical angles

8. 5x + 10 = 70

    5x = 60

    x = 12

    5(12) + 10 = 60 + 10 = 70

<1 and <3 should be 110

<2 and <4 is 70

d? maybe

step-by-step explanation:

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
