Question

PLEASE HELP :))

Answer 1

The measure of the side PR in PQR is 8.07 units and the measure of angle J in JKL is 35.30 degree.

What is the triangle?

The triangle can be defined as a three-sided polygon in geometry, and it consists of three vertices and three edges. The sum of all the angles inside the triangle is 180°.

Applying cos law in the triangle PQR:

$\rm PR = \sqrt{5^2+9^2-2(5)(9)cos63}$

PR = 8.07 units

Applying sin law in the triangle, JKL:

$\rm Angle \ J = sin^{-1}[sin 52 \ (\dfrac{11}{15})]$

Angle J = 35.30 degree

Thus, the measure of the side PR in PQR is 8.07 units and the measure of angle J in JKL is 35.30 degree.
