Question

A sailmaker is making a right triangular sail. One of the angles in the sail is 47°. What is the measure of the unknown angle?

Answer 1

Dude this is so easy! Wait a sec lemme draw!

Answer 2

The draw button is not working so....

The sum of all angles in a triangle is = 180

Right angle triangle has one 90 angle.
The second angle is given = 47°

So we will take unknown angle = x

90 + 47 + x = 180
137 + x = 180
x = 180 - 137
x = 43°
