Question

Find the value of x

Answer 1

26

Explanation:

(6x + 4) + (4x + 6) = 90

180 - (4x + 6) = (6x + 4) + 90

Rearrange the equation.

180 - (-90) = (6x + 4) + (4x + 6)

270 = 6x + 4 + 4x + 6

270 = 10x + 10

260 = 10x

26 = x

I don't know if this is correct, so I apologize if its wrong.

Answer 2

x = 8

Explanation:

According to the picture,

These given two angles are complementary. That is, those two angles are added up to 90°.

Therefore,

( 6x + 4 ) + ( 4x + 6 ) = 90

Combine like terms.

6x + 4 + 4x + 6 = 90

10x + 10 = 90

Subtract 10 from both sides.

10x = 90 - 10

10x = 80

Divide both sides by 10.

x = 8
