Explanation:
since the 2 triangles are congruent, that means that all corresponding angles and lengths are the same between the 2 shapes.
PS corresponds to HC
so,
39 = 2x - 7
46 = 2x
x = 23
R corresponds to F
so,
13y - 1 = 90
13y = 91
y = 7
H corresponds to S.
remember, the sum of all angles in a triangle is always 180°.
so,
6z - 4 = 180 - 28 - 90 = 62
6z = 66
z = 11
