Question

Find the measure of acute angle of a right angle triangle when one angle is 60°

Answer 1

30°

Step-by-step explanation:

What we know:

• We know that all angles in a triangle add up to 180°
• We know that 1 of the 3 angles is 90°
• We know that 1 one of the 3 angles is 60°

What to find out:

• What the last angle equals

We used the information we know to give us this equation.

90°+60°+x=180°

We add 90° and 60° to give 150°

150°+x=180°

x must therefore be 30°

Answer 2

30 degrees.

Step-by-step explanation:

Let the acute angle be x.

Then as the 2 acute angles in a right triangle sum to 90 degrees,

x = 90 - 60

= 30.
