Answer:
Answer 44
Step-by-step explanation:
I'll do some of it. You can supply some of the vocabulary.
<Q = 56 degrees The triangle is isosceles.
<PRQ = 180 - 56 - 56 All triangles have 180 degrees.
<PRQ = 68 Do the subtraction
<PRQ = <SRT Why is this so? You have the term.
<TRS = 68 degrees The reason is the same as the last part.
<T = <RST The triangle is isosceles (2 equal angles)
<T = 68 Two equal angles = the same degrees
S = 180 - <T - < RST S is the left over from the 2 equal angles.
S = 180 - 68 + 68 Substitute.
S = 44
8 minus 3 equals 5
Negative 1 minus 9 is negative 10
5 times negative 10 is <u>negative 50.</u>
I do believe the answers in a row are A: x, B: 40, C: 12, D:y
