Answer:
56.6m
Step-by-step explanation:
Using SOH = opp/hyp
Where θ = 45°
Hpy = 80m
Opp = ?
Sin θ = opp/hpy
Sin 45 = opp/ 80
Sin 45 × 80 = opp
0.7071 × 80 = opp
Opp = 56.568
~ 56.6m
Hence the height of the top of the tree is 56.6m
The answer is D

Answer:
-4.88
Step-by-step explanation:
-5+(-3) = (-8)
7/10 = 98/140
3/7 = 60/140
15/4 = 525/140
525/140 + 60/140 + 98/140 = 683/140
683/140 = 4 123/140
4 123/140 = 4.88 (2dp)
4.88+(-8) = -4.88
Answer:
P = 60 inches
Step-by-step explanation:
Perimeter is the distance around the outside of a shape. So, to find perimeter, add up all the sides.
The side lengths were given, add them:
15 + 20 + 25
= 60
The perimeter is 60 inches.
