PQ=RQ and PS=RS
What does b=?

The measure of angle b is 15 degrees and this can be determined by using the properties of the isosceles triangle.

Given :

The following steps can be used in order to determine the measure of angle b:

Step 1 - According to the given data, it can be concluded that triangle PQR and triangle PSR are isosceles triangles.

Step 2 - Apply the sum of interior angle property on triangle PQR.

Step 3 - Now, apply the sum of interior angle property on triangle PSR.

Step 4 - Now, the measure of angle b is calculated as:

The measure of angle b is 15 degrees.

y=-2.5x+12.5

step-by-step explanation:

5y=2x+10

y=0.4x+2

slope=-2.5

5=-2.5*3+b

b=12.5
