Find the measures of the interior angles.
what is angle B and C?

Answer:
x = 42
Step-by-step explanation:
The square at ∠C means it is a right angle (90°). The sum of the angles of a triangle is 180°. Use the information to solve for ∠B.
[tex]x+48+90=180\\x+138=180\\x=42[/tex]
Answer:
B = 41 degreed
Step-by-step explanation:
Square of C = 90degrees
A = 49degrees
90 + 49 = 139degrees
180degrees - 139degrees = 41 degrees
