Can a triangle be formed with side lengths 15, 20, and 24? Explain.

Yes

Step-by-step explanation:

According to triangle inequality, the sum of any two side must be greater than the third side. So we take the two smallest side and find the sum

15 + 20 > 24

YES it can

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

answer: approximately 206 bones

i hope this u out a branlist and a would be greatly appreciated :
