Sure, here's the step-by-step work to find the measures of angles X, Y, and Z:
Given:
△RST ∼ △XYZ
m∠R = 18°
m∠S = 75°
Step 1: Corresponding angles are congruent
Since △RST ∼ △XYZ, the corresponding angles are congruent. This means that ∠R and ∠X are congruent, and ∠S and ∠Y are congruent.
So, m∠X = 18° and m∠Y = 75°.
Step 2: Using the sum of angles in a triangle
The sum of the angles in a triangle is always 180°.
Let's find the measure of ∠Z.
m∠R + m∠S + m∠T = 180° (sum of angles in △RST)
Substituting the given values:
18° + 75° + m∠T = 180°
Combining like terms:
93° + m∠T = 180°
Subtracting 93° from both sides:
m∠T = 180° - 93°
m∠T = 87°
So, m∠Z = 87°.
Therefore, the final measures of angles X, Y, and Z are:
m∠X = 18°
m∠Y = 75°
m∠Z = 87°
Given:
△RST ∼ △XYZ
m∠R = 18°
m∠S = 75°
Step 1: Corresponding angles are congruent
Since △RST ∼ △XYZ, the corresponding angles are congruent. This means that ∠R and ∠X are congruent, and ∠S and ∠Y are congruent.
So, m∠X = 18° and m∠Y = 75°.
Step 2: Using the sum of angles in a triangle
The sum of the angles in a triangle is always 180°.
Let's find the measure of ∠Z.
m∠R + m∠S + m∠T = 180° (sum of angles in △RST)
Substituting the given values:
18° + 75° + m∠T = 180°
Combining like terms:
93° + m∠T = 180°
Subtracting 93° from both sides:
m∠T = 180° - 93°
m∠T = 87°
So, m∠Z = 87°.
Therefore, the final measures of angles X, Y, and Z are:
m∠X = 18°
m∠Y = 75°
m∠Z = 87°
