Question

In triangle PQR , Angle P = 90° and Angle R = 30° , find PR and QR if
PQ = 4cm​

Answer 1

Answer:

RQ= 8cm , PR = 4√3 cm

Step-by-step explanation:

In ∆PQR, R is 30, P is 90

Hence Q is 60

By 30-60-90 degree theorem,

PQ = 1/2 ×hyptRQ

4 = 1/2 × RQ

RQ = 8 cm

Similarly

RP =√3/2× hypo RQ

8×√3/2 = RP

RP = 4√3 cm
