Answer:

a) 60° b) 50°

Explanation:

The measurements of a triangles total angles is always equal to 180.

In question a), an Equilateral triangle is shown. Which means all the sides and angles are equal. So you divide 180 by 3, which equals 60.

In question b), an Isoceles triangle is shown. Which means two of the three sides and angles are equal. The other angle is already given: 80.

All you need to do now is subtract 80 from 180 and divide the diffrence by 2.

So, 180-80=100

100/2=50

S=50

Q=50

I hope this helped! :D
