Question

What is the value of t

Answer 1

89°

Explanation:

2t-46+(180-t-43)

t+180-89

t+91=180°

t=89

Answer 2

t=89

Explanation:

`(t-46)+(t)+(180-(t+43)) = 180\\\\t-46+t+180-t-43=180\\\\t=180-180+46+43\\\\t=89`

(t-46)+(t)+(180-(t+43)) = 180° because the sum of angles of a triangle is 180°.
