Answer 1

Answer:

x = 39°

Step-by-step explanation:

The triangle shown is a right angle triangle having angles 90°, 51° and x°.

Sum of interior angles of a triangle = 180°, therefore:

$90 + 51 + x = 180$

Add like terms

$141 + x = 180$

Subtract 141 from each side

$141 + x - 141 = 180 - 141$

$x = 39$

x = 39°
