Question

If two angle measurements of a triangle are 90 and 60 what is the third angle?

please show all steps

Answer 1

Given

• Two out of three angles of a triangle measures 90° & 60° respectively

To find

• The third angle

We know that,

• Measure of all three angles of a triangle = 180°

Let the third angle be ,'x'

then,

• x + 90° + 60° = 180°
• x + 150° = 180°
• x = 180° -150°
• x = 30°

Hence,the third angle would measure 30°
