The figure below shows a triangular wooden frame ABC. The side AD of the frame has rotted and needs to be replaced:

What is the length of the wood that is needed to replace AD?

8.1 inches
6.2 inches
5.9 inches
7.4 inches

d) -1

step-by-step explanation:

the two may have that, even a breakdown is probably offered

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.

just get this app called photo math it should be able to do those
