When two angles are complementary what is the sum of their measures is 90 degrees. two complementary angles have the measure of
galben [10]
2x - 10 + 3x - 10 = 90
5x - 20 = 90
5x = 90 + 20
5x = 110
x = 110/5
x = 22

2x - 10......2(22) - 10 = 34 <== one angle
3x - 10......3(22) - 10 = 56 <== the other angle

Question 1:

<span>5z – 9 = 36

5z = 45

z = </span>\frac{45}{5}

z = 9

Hence, the answer is D.

Question 2:

<span>5(2z + 4) = 0
</span><span>
10z + 20 = 0

10z = -20

z = </span>\frac{-20}{10}
<span>
z = -2

Hence, the answer is A.

Question 3:

4a + 3(a + 1) = 24

4a + 3a + 3 = 24

7a = 21

a = </span>\frac{21}{7}

a = 3

Hence, the answer is B.

Question 4:

<span>3(4x + 5) = 12

12x + 15 = 12

12x = 12 - 15

12x = -3

x = </span>\frac{-3}{12} = - \frac{1}{4}

Hence, the answer is A.

Question 5:

<span>4x – 8 – 4x = 9

-8 </span>≠ 9

Hence, the answer is A.
