Answer:
75°
Step-by-step explanation:
∠DGF = 2* ∠DEF
10x + 50 = 2(9x - 15)
10x + 50 = 18x - 30
50 = 18x - 30 - 10x
50 = 8x - 30
8x - 30 = 50
8x = 50+30
8x = 80
x = 80/8
x = 10
∠DEF = 9x - 15
= 9*10 -15
= 90 - 15
= 75°
Rigid transformation preserves both the side lengths and angle measures of a polygon.
Answer:
2/3
Step-by-step explanation:
5 black
3 green (not black)
3 blue (not black)
4 yellow (not black)
there are 5 black and 10 not black out of a total of 15 marbles.
there are 10/15 that are not black. Reduced 2/3.
21 - 13.50= 7.50
so based on what your question is asking, Serena makes $7.50 more than Gabe per hour.
