Question

What is the value of t ?

Answer 1

Answer:90

Explanation:

Right angles are all 90

Answer 2

The total degree of a line equals 180, so you will add 50 and 40 to get 90, and you will subtrade 90 from 180 to get 90.

180-90=90

also, the little square on the bottom next to the t means that it is a right angle (90 degrees)
