Answer:
x = 30°
2x = 60°
3x = 90°
Step-by-step explanation:
GBF = CBD (opposite angle)
; 2x+x+3x = 180° (Size of straight angle)
6x = 180
x = 180÷6
x = 30°
substitution x in 2x ; 2×30 = 60°
substitution x in 3x ; 3×30 = 90°
hope it helps ☺️

add -44+8
and u get 8x+36=-36
subtract the 36 on both sides and leave u with
8x=-72
divide 8 on both sides

i dont think this make sense but hope this helps
Answer:
15/56
Step-by-step explanation:
5 people have a license
3 people don't
? = Probability that first person has a license and second does not
We can divide the problem into two sections, the first being the probability of the first person having a license, and the second section is the probability that the second person doesn't have a license.
P1 = Probability of the first person having a license, there are 5 out of 8 person having a license, thus P1 = 5/8.
P2 = Probability of the second person having a license. There are 3 people not having a license, out of 8-1 = 7 persons available, since one is taken already from the first choice, therefore P2 = 3/7.
P1 and P2 are dependent events, thus P(1,2) = P1 * P2.
P(1,2) = P1 * P1 = 5/8 * 3/7 = 15/56
