Since triangle ABC is similar to triangle SRT, their corresponding angles are congruent. Therefore, m∠B = m∠R.
From the given information, we know that m∠R = 56 degrees.
Therefore, m∠B = 56 degrees.
Use the image to answer the question.
An illustration shows two right triangles with congruent corresponding angles. Triangle A B C is larger than triangle S R T. In triangle A B C, angle A measures 90 degrees, angle B does not have a measurement, and angle C measures 34 degrees. In triangle S R T, angle S measures 90 degrees, angle R measures 56 degrees, and angle T measures 34 degrees.

In △ABC , m∠A=63° and m∠C=99° . What is the measure of angle B ?
To find the measure of angle B, we can use the fact that the sum of the angles in a triangle is always 180 degrees.
m∠A + m∠B + m∠C = 180°
Given that m∠A = 63° and m∠C = 99°:
63° + m∠B + 99° = 180°
Combining like terms:
m∠B + 162° = 180°
Subtracting 162° from both sides:
m∠B = 18°
Therefore, the measure of angle B is 18 degrees.
m∠A + m∠B + m∠C = 180°
Given that m∠A = 63° and m∠C = 99°:
63° + m∠B + 99° = 180°
Combining like terms:
m∠B + 162° = 180°
Subtracting 162° from both sides:
m∠B = 18°
Therefore, the measure of angle B is 18 degrees.
△LMN is isosceles, with ∠M≅∠L and m∠L=36° . What are the measures of angles M and N ?
Since triangle LMN is isosceles, its base angles ∠M and ∠N are congruent.
Given that ∠L = 36°, and ∠M ≅ ∠L, we know that ∠M is also 36°.
Since the sum of the angles in a triangle is always 180°:
∠L + ∠M + ∠N = 180°
36° + 36° + ∠N = 180°
72° + ∠N = 180°
Subtracting 72° from both sides:
∠N = 108°
Therefore, the measures of angles M and N are 36° and 108°, respectively.
Given that ∠L = 36°, and ∠M ≅ ∠L, we know that ∠M is also 36°.
Since the sum of the angles in a triangle is always 180°:
∠L + ∠M + ∠N = 180°
36° + 36° + ∠N = 180°
72° + ∠N = 180°
Subtracting 72° from both sides:
∠N = 108°
Therefore, the measures of angles M and N are 36° and 108°, respectively.
