The height of the building to the nearest tenth of a meter is; 13 m
<h3>How to make use of Cosine Rule?</h3>
The slant line from the top of Trevor's head to the base of the building is gotten from Pythagoras theorem;
15/x = sin 36°
x = 15/sin 36
x = 25.52 m
Angle between that slant line and base of building is;
90 - tan⁻¹(1.5/14) = θ
θ = 83.88°
Remaining angle of the bigger triangle is;
180 - (36 + 83.88) = 60.12°
Thus, if the height of the building is h, then;
h/sin 36 = 25.52/sin 60.12
h = 13 m

5 is a constant. (it has no variables)
x + 2 is not a constant. It does, however, have two terms, x and 2.
(terms are seperated by addition/subtraction)
This rules out a and b.
As for c... 5(x+2) implies <em>multiplication</em>, which would be a product, not a sum.
d. The product of a constant factor 5 and a 2-term factor x+2
Answer:
Step-by-step explanation:
Side A is the longest side
Side B is half of A = A/2
Side C is 8m less than A = A-8
Perimeter of traingle = A+B+C
52 = A + A/2 + A-8
Collect like terms
52+8= A+A/2+A
60 = 5/2 A
Divide 60 by the coefficient of A
60÷5/2 = A
60×2/5= A
A=24m
Substitute the value of A into the expressions for sides B and C
Side B =A/2=24/2=12m
Side C =A-8=24-8=16m
The sides of the triangle are 24m, 12m and 16m
D
