what is the value of t?
Answer
Explanation:
Step1: Identify angle - addition relationship
The large angle is composed of two non - overlapping smaller angles. The measure of the large angle is the sum of the measures of the two smaller angles. So, $t+30^{\circ}=49^{\circ}$.
Step2: Solve for $t$
Subtract $30^{\circ}$ from both sides of the equation: $t = 49^{\circ}-30^{\circ}$.
Answer:
$19^{\circ}$
