a=10
Step-by-step explanation:
Answer:
x=-0.688
Step-by-step explanation:
-2496-3744x+36 = -759x-414-10x
-2460-3744x = -769x-414
-2975x = 2046
Alrighty. If there's 3 angles that are on one linear line, they all must add up to 180, because they would wall be supplementary angles (they all add up to 180).
So, we know that the Angle FCA is 90 degrees, and we know that ACB is 66 since they said so. So, we will add them up, then subtract it from 180. So,
BCD + 66 + 90 = 180
BCD + 156 = 180
BCD = 24
(P.S, that means the angle FCE will be the same because of vertical angle theorem)
Ascend means rise so you want to find out its current postilion so you subtract
36 - 16= 20 so
The submarine's current position is 20 ft
Part 1: 14 because 52+ 74 equals 126 divided by 9 equals 14
part 2:7 because 52+ 74 equals 126 divided by 18 equals 7.
