Answer:
33
Step-by-step explanation:
You find the measure of B, which is 180 - (93 + 58) = 29 degrees
You use the law of sines which is 16/sin(29) = (BC)/sin(93)
You multiply both sides by sin(93) and get:
sin(93)*16/sin(29) = BC
You plug this into a calculator and get:
32.9574164555, which is approx. 33
Answer:
The general formula for the total surface area of a regular pyramid is T. S. A. =12pl+B where p represents the perimeter of the base, l the slant height and B the area of the base.
if the base is 12cm and the slant heights is 10cm then the total surface area is 168cm²
Pytharorean therum...can only be used on right triangles
a^2 + b^2 = c^2...a and b r ur legs and c is ur hypotenuse
10^2 + 24^2 = c^2
100 + 576 = c^2
676 = c^2
sqrt 676 = c
26 = c <== ur hypotenuse is 26 cm
Their original price was 3.50, meaning that 3.50 is 100% of the price. We can find the percentage of the new price, 2.80, by using ratios.
3.50 100%
2.80 x%
x = 100% * 2.80 / 3.50 = 80%
The new price, 2.80, is 80% of the original price. Since 100% - 80% is 20%, this means that the decrease of the price was 20%.
