ABC is a isosceles triangle
AC = BC
so
<A = <B
2x - 20 = x + 8. solve for x
subtract x to both sides
2x - 20 - x = x + 8 - x
x - 20 = 8
add 20 to both sides
x - 20 + 20 = 8 + 20
simplify
x = 28
<A = <B = 28 + 8 = 36
<C = 180 - 2(36)
<C = 180 - 72
<C = 108
Answer
B. 108 degrees
Answer:
50 deg
Step-by-step explanation:
In an right triangle, the acute angles are complementary. That means their measures have a sum of 90 deg.
m<C + m<B = 90
7x - 20 + 4x = 90
11x = 110
x = 10
m<ACB= 7x - 20
m<ACB = 7(10) - 20
m<ACB = 70 - 20
m<ACB = 50
Answer: m<ACB = 50 deg
Answer:
D. 5
Step-by-step explanation:
If you look at all the data collected, the time goes up to 5 seconds but with each second the height goes up and down drastically. With all of it is would have to be 5 seconds because that is how many seconds they recorded the fountain being on for.
Hope this helps :3
