Question

HELP MEEE WITH THESE MATH PROBLEMS!!!

Answer 1

Answer:

1) 39

2) 59

3) 53

4) 38

5) 9

6) 12

7) 15

8) 11

Step-by-step explanation:

if the angles together is a right angle than you just subtract the angle that is known from 90 and you get your other angle.

1) 90 - 51 = b = 39

2) 90 - 31 = b = 59

3) 90 - 37 = b = 53

4) 90 - 52 = b = 38

5) 90 - 56 = 34

34 = 3x + 7

3x + 7 - 7 = 3x

34 - 7 = 27

3x = 27

3x  / 3 = x

27 / 3 = 9

6) 90 - 48 = 42

42 = 3x + 6

3x + 6 - 6 = 3x

42 - 6 = 36

3x = 36

3x / 3 = x

36 / 3 = 12

7) 90 - 47 = 43

43 = 2x + 13

2x + 13 - 13 = 2x

43 - 13 = 30

2x = 30

2x / 2 = x

30 / 2 = 15

8) 3x +  5x + 2 = 90

8x + 2 = 90

8x + 2 - 2 = 8x

90 - 2 = 88

8x = 88

8x / 8 = x

88 / 8 = 11
