Answer:

106°

Step-by-step explanation:

Explanation:

BEAR can be considered as two triangles back to back. The sum of the internal angles of a triangle is 180°

So the sum of the internal angles of BEAR = 2 × 180

= 360°

Let angle R be denoted as R, from the above:

92 + B = R + 74 = 180

R = 180 - 74

= 106°
