Question

if two angles are measure (x+3) (2x-a) are complementary then find x​

Answer 1

(x+3)+(2x-a) = 90 degrees [since they are complumentary]

two complementary angles add up to 90 degrees

x+3+2x-a=90

3x+3-a = 90 degrees

3x-a = 90 -3

3x -a =87 degrees

x-a = 87/3 degrees

x-a= 29 degrees

x = 29 + a degrees

that's all mark as brainliest

Answer 2

Find the value of x:

Step-by-step explanation:

$\ Given \ value:\\\\\ angle:\\\\(x+3) (2x-a)\\\\Find:\\\\\x= ?\\\\\ Solution:\\\\\ complementary \ angle \ condition \\\\\ addition \ of \ angle = 90\\\\ (x+3)+ (2x-a) =90\rightarrow (x+3+2x-a)=90\\\\\rightarrow (3+3x-a)=90\\\\\rightarrow (3x-a)=90-3\\\\\rightarrow (3x-a)=87\\\\\rightarrow x=\frac{87-a}{3}$
