Step-by-step explanation:
The triangles are similar by the AA postulate, thus the ratios of corresponding sides are equal, that is
= , substitute values
= ( cross- multiply )
20PR = 120 ( divide both sides by 20 )
PR = 6 → C
4x+10=90
4x=80
x=20
Why 90°? This is because the angle subtended in a semi-circle to the circumference is 90°.
