Answer:
Perimeter- 26cm
Area- I Don't know sorry. I'll comment if I figure it out
23) Store A: y=6.30÷2
y=3.15
Store B: y=3.2
Store C: y=3.25x
y=3.25 so Store A sells the cheapest so (A) is the answer
24) the area uses half of the diameter, not the whole diameter. so the answer is 5.5pi^2 (B)
25) 1/2 × 1/2 = 1/4 × 1/2 = 1/8 (D)
26) was done correctly and (D) is the correct answer
27) 2 (x-3) +1 =19
2 (x-3) = 19 - 1
(x-3) = 18 ÷ 2
x-3 = 9
x= 9+3
x=12 (D)
A = 1/2bh
40 = 1/2 x^2
x^2 = 80
x = 8.9
all i can really say is it is a y angle
<u>Given:</u>
The angle of elevation from the point on the ground to the top of the tree is 34° and the point is 25 feet from the base of the tree.
We need to determine the height of the tree.
<u>Height of the tree:</u>
Let the height of the tree be h.
The height of the tree can be determined using the trigonometric ratio.
Thus, we have;

Substituting the values, we get;

Multiplying both sides by 25, we have;



Rounding off to the nearest tenth of a foot, we get;

Thus, the height of the tree is 16.9 feet.
Hence, Option B is the correct answer.
