Question

If (x+ 8) and (2x + 25) are complementary, then x is equal to
A. 19
B. 20
C. 17
D. 16​

Answer 1

Answer:

your's Answer:(A).19

Answer 2

Answer:

option A.19

Step-by-step explanation:

As they are complementary angles, their sum is 90 degree

so,

(x+8)+(2x+25) should be equal to 90

(x+8)+(2x+25)=90

x+8+2x+25=90

3x+33=90

3x=90-33

3x=57

x=57/3

therefore, x=19
