Question

What is the measure of RSP in the diagram below

Answer 1

Remark

All triangles have 180o. There are no exceptions to this statement.

Let the unknown angle = x

43 + 79 + x = 180

122 + x = 180 Subtract 122 from both sides

x = 180 - 122

x = 58 <<<< answer

The next problem should be a triangle. Look at the base which is a triangle. Any horizontal plane will cut out a similar triangle to the base.

Answer 2

The answer would by 58. I hope this helps!!
