Draw a right triangle ABC with, the point where the top touches the ground and one leg, BC, the stump, measuring 14 ft.
The height of the tree = hypotenuse + stump BC (14 ft)
If the ∠ of inclination = 43°, then ∠ CAB = 37°
Now let's apply the law of sine:
sin 37°/14 = sin 43°/AB →and AB = 14.sin 43°/sin 37° = 15.86
Hypotenise² = AB² + CB²
Hypotenuse² = 15.85² + 14² = 447.22 → and Hypotenuse = 21.14 ft
Tree Height = hypotenuse + stump = 21.14 + 14 ≈ 35 ft
Answer:
(a+b)(c+d)=a c+a d+b c+b d is the formula
Step-by-step explanation:
Answer:
9 3/4 cubic units
Step-by-step explanation:
The formula for the volume of a rectangular prism =
Length × Width × Height
From the question:
Length = 3 units
Height = 3 1/4 units
Width = 1 unit.
Volume of the prism =
3 units × 3 1/4 units × 1 unit
= (3 × 13/4 × 1 )cubic units
= 39/4 cubic units
= 9 3/4 cubic units
The total volume of the rectangular prism = 9 3/4 cubic units

Equation Step by Step</h3>
sin(4(3.141593^3)+3.141593^4)
sin((4)(31.006277)+3.141593^4)
sin(124.025107+3.1415934)
in(124.025107+97.409091)
sin(221.434198)
=0.998844
Tbh, might be wrong on this one. I'm on the road so didn't double-check my answer.
Answer:
I think it's A I hope this help you
