Answer:
∡1 = 82°
Step-by-step explanation:
The sum of the angles of a triangle is 180°.
You could find the missing angle by the following steps:
49° + 49° + x = 180°
x is the missing angle ∡1. Simplify the like terms.
98° + x = 180°
Bring 98° to the other side: makes it -98. This is done to find the value of x.
x = 180° - 98°
x = 82°
