The height of the tree and the building are 7.6 m and 28.6 m respectively.
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
Two triangles are similar if they have the same shape and the ratio of their corresponding sides are in the same proportion.
Triangle BGD, CHD and AFD are similar triangles.
CH = 1.6, DH = 8, GH = 30, GF = 105
FH = GF + GH = 105 + 30 = 135
FD = FH + DH = 135 + 8 = 143; GD = 30 + 8 = 38
Hence, using similar triangles:
BG/CH = GD / DH
BG / 1.6 = 38/8
BG = 7.6 m
Also:
building/CH = DF / DH
building / 1.6 = 143/8
building = 28.6 m
The height of the tree and the building are 7.6 m and 28.6 m respectively.

Answer:
a. 10
Step-by-step explanation:
x is the radius and any line drawn from centre of the circle to the ends of circle is radius.
using pythagoras theorem:
base^2+height^2= Hypotenuse^2 (over here hypotenuse is radius)
6^2+8^2=x^2
36+64=x^2
100=x^2
x= root of(100)
x=10
Hello from MrBillDoesMath!
Answer:
Range = { -11, -5, 4, 10}
Discussion:
g(x) = 3x- 5 =>
g(-2) = 3(-2) -5 = -6 -5 = -11
g(0) = 3(0) - 5 = 0 -5 = -5
g(3) = 4(3)-5 = 9-5 =4
g(5) = 3(5)-5 =15-5 = 10
So the range is { -11, -5, 4, 10}
Thank you,
MrB
So first you need 1 adult with every 6 children so do 6*4 and got 24. From that you get 4 adults with 2 leftover children. For the other class which has 28 children, you would still need 4 adults. Now since you said the teacher is included as an adult only 3 more are needed for the trip, and that is your answer.
