Ijust need for 3 questions! write an expression for the perimeter of the triangle shown below: a triangle is shown with side lengths labeled 2.3x plus 14, 2x, and negative 0.2x plus 15. 4.1x + 29 4.1x − 29 4.5x + 29 4.5x − 29 which expression is equivalent to 1/5m − 20? 1/5(m − 4) 1/5(m − 100) 5(m − 4) 5(m − 100) write an expression that is equivalent to 3/5 (3y + 15). three over fivey + 9 three over five y + 15 nine over fivey + 9 nine over fivey + 15

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

a .4y4

hope this !
