Answer:

x = 7

3x + 17 = 38

6x + 10 = 52

Explanation:

Comment

Given the two lines are perpendicular. The ray separates them so that two smaller angles are formed which add up to 90 degrees. They are called complementary angles.

Given

<3x + 17

<6x + 10

The two lines are perpendicular.

Equation

(3x + 17) + (6x + 10) = 90

Solution

It the two lines are perpendicular the meet at right angles. A right angle 90 degrees.

(3x + 17) + (6x + 10) = 90 Remove the brackets.

3x + 17 + 6x + 10 = 90 Combine like terms on the left.

9x + 27 = 90 Subtract 27 from both sides.

9x + 27-27 = 90-27 Combine

9x = 63 Divide both sides by 9

9x/9 = 63/9

x = 7
