Mathematics
1 answer:
Alja [10]3 years ago
6 0

Answer:

b = 25.03,

c = 32.67   to the nearest hundredth.

Step-by-step explanation:

To find b and c you can use the trigonometry of a right angled triangle.

tan 50 = b / 21

b = 21 tan 50

b =  25.03

cos 50 = 21 / c

c = 21 / cos 50

= 32.67

Hi, thank you for posting your question here at Brainly.

All you have to do to acquire the equation is to substitute the variables to the formula for A and simplify. Since A = 1/2*b*h and h = bsin(C), then A can be in terms of one variable only, which is b.

A = 1/2*b*bsin(c)
A = 1/2*b^2*sin(C)

Pavlova-9 [17]

Answer:

45 square feet

Step-by-step explanation:

we know that

The volume of the pedestal (rectangular prism) is given by the formula

V=Bh

where

B is the area of the rectangular base of pedestal

we have

V=405\ ft^3\\h=9\ ft

substitute the given values in the formula and solve for B

405=B(9)

B=405/9\\B=45\ ft^2
