Question

Triangle PQR is a right triangle.

Answer 1

Answer:

The FOURTH option is correct.

Therefore the Equation used to find the measure of Angle Q is

$90=x+2x$

Step-by-step explanation:

Given:

Triangle PQR is a right triangle.

Angle P = 90°,

angle Q = x°

angle R = 2 x°

To Find:

Equation for Angle Q = ?

Solution:

Triangle sum property:

In a Triangle sum of the measures of all the angles of a triangle is 180°.

$\angle P+\angle Q+\angle R=180$

Substituting the values we get

$90+x+2x=180\\x+2x=180-90\\x+2x=90\\90=x+2x$ ......As required

Therefore the Equation used to find the measure of Angle Q is

$90=x+2x$

Answer 2

Answer:

The answer 180=3x+90
