Answer:
The angles are 65° and 115°
Step-by-step explanation:
Let
x,y ----> the two side interior angles of two parallel lines
we know that
x+y=180° ----> equation A
x-y=50° ----> equation B
Adds equation A and equation B
x+x=180°-50°
2x=130°
x=65°
Find the value of y
x+y=180° -----> 65°+y=180° ----> y=180°-65°=115°
therefore
The angles are 65° and 115°
Answer:
A. f(x) = 1.75x
Explanation:
Every time you buy add a rose, the price increases 1.75
4.25 -> 6
9.50 -> 11.25
4b+21=-3b+21+7b
4b+21=4b+21
it means that the expression shows an identity
Answer:
Pythagorean theorem which is a²+b²=c2
9²+12²=c²
225=c2
c=√225
c=15
