Solving a is the process of calculating unknown side lengths or angle measures of a triangle if certain of the side lengths and/or angle measures are known. square polygon triangle problem

option: C is correct (i.e. Triangle)

Step-by-step explanation:

Solving a is the process of calculating unknown side lengths or angle measures of a triangle if certain of the side lengths and/or angle measures are known.

Triangle is correct; because To SOLVE A TRIANGLE means to know all three sides and all three angles.

Hence option : C is correct

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

x-3y=4
