Answer:

x = 52

Step-by-step explanation:

Since we know that all angles of a triangle add up to 190 degrees,

Angle RQS = 180 - 90 - 34

= 56 degrees

Angle PQS = 180 - 56 (Angles on a straight line add up to 180)

= 124 degrees.

Therefore, x + 72 = 124

x = 52

Answer:

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the two opposite side

: 90° + 34° = x + 72°

x = 90° + 34° - 72°

x = 52°

Since it is given that AB ≅ AC, it must also be true that AB = AC. Assume ∠B and ∠C are not congruent. Then the measure of one angle is greater than the other. If m∠B > m∠C, then AC > AB because of the triangle parts relationship theorem. For the same reason, if m∠B < m∠C, then AC < AB. This is a contradiction to what is given. Therefore, it can be concluded that

Answer: Angle (B) is Congruent to Angle (C)
