Answer:
To find the area of a triangle, multiply the base by the height, and then divide by 2. The division by 2 comes from the fact that a parallelogram can be divided into 2 triangles. For example, in the diagram to the left, the area of each triangle is equal to one-half the area of the parallelogram.

Step-by-step explanation:
the formula for volume of a cylinder is :
r=d/2
r = 7/2
h= 10
v= 22/7×7/2×10
v= 110cm³
Answer:
A
Step-by-step explanation:
ƒ(x) = 2x2 + 5x – 8
g(x) = –x2 + 6x
(ƒ – g)(x)=2x2+5x-8-(-x2+6x)
=2x2+5x-8+x2-6x
=3x2-x-8
Answer:
56.96°
Step-by-step explanation:
The set up will give a right angles triangle where;
The height of the sky scraper = hypotenuse side = 396m
The length of the shadow will be the opposite = 332m
According to the SOH trig identity
sin theta = opp/hyp
sin theta = 332/396
sin theta = 0.8383
theta = arcsin 0.8383
theta = 56.96°
Hence the sun is at 56.96° above the horizon
