Since <A = <D and <B = <E, it must be true that the third angles <C = <F (the triangles are similar).
If <C = x and <F = 2x-30 then you need to find x for which <C = <F is true:
x = 2x-30
and that holds for x=30
So m<C=30 degrees
Answer: 4
Step-by-step explanation:
The procedure is pretty basic. First you have to substitute what you know in the equation. So as you know f(x)=18, just substitute f(x) by 18, leaving it like 18 = 3x + 6.
Then you have to start to move things around. First start with the + 6 that is adding, so it moves to the other side as a substraction giving 18 - 6 = 3x -> 12 = 3x. The next step is to get rid of that 3, so because it's multiplying the x, it moves to the other side as a division leaving you with 12 ÷ 3 = x -> 4 = x. There you have the answer! For a value/y of 18 in that function, the x is 4
A = -2 (reflection)
H = +3 (shifts to the right)
K = -1 (shifts downward)
Answer:
Step-by-step explanation:
The triangle formed by the lamp post and the (24+6)foot side on the ground is similar to the right triangle formed by the person of height h and his 6 foot shadow.
H/25=6/36
H=5
