Question

In the figure below, if the angle is right what is the value of x?
​

Answer 1

x = 50

Explanation:

Since the angle is right = 90°, then

40 + x = 90 ( subtract 40 from both sides )

x = 50

Answer 2

`\boxed{\sf x = 50\ degrees}`

Explanation:

x = 90 - 40 [Complementary angles add up to 90 degrees]

x = 50 degrees
