In △QRS , ∠R is a right angle and the measure of ∠S is 22° . image c13b1e8dceb043b08b2dd5d2c53d54b5

Which equation can be used to calculate the measure of ∠Q ?

x+22=90

22−x=90

x+22=180

22−x=180

X+22=180

Step-by-step explanation:

X+22=180 or 22+x=90

$450

step-by-step explanation:

first, you have to multiply 150x2=300

next, you have to add 150+300= 450

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq
