Question

a triangle has interior angle measures of t, 54°, and 54°. what is the value of t? t =

Explanation:

Step1: Recall angle - sum property

The sum of interior angles of a triangle is 180°. So, $t + 54^{\circ}+54^{\circ}=180^{\circ}$.

Step2: Simplify the equation

$t+108^{\circ}=180^{\circ}$.

Step3: Solve for t

Subtract 108° from both sides: $t = 180^{\circ}-108^{\circ}$.

Answer:

$72$
