Answer:

1960 cm^2

Step-by-step explanation:

Surface area:

Area of cross section x 2 = 1/2 x 20 x 21 x 2 = 420 cm^2

Area of slope = 29 x 22 = 638cm^2

Area of base = 22 x 20 = 440cm^2

Area of back = 21 x 22 = 462cm^2

Total Surface area = 462+440+638+420 = 1960cm^2

Hope this helps

the captain of a boat knows that the lighthouse on the coast is 200 feet tall. he measures the angle of elevation to the top of

krek1111 [17]

Answer:

The boat is 5727.25ft far from the coast

Step-by-step explanation:

Refer the figure given.

We need to find how far is the boat from the coast = AB

Angle of elevation = 2°

The lighthouse on the coast is 200 feet tall, AC = 200 ft

We have

$tan2=\frac{AC}{AB}=\frac{200}{AB}\\\\AB=\frac{200}{tan2}=5727.25ft$

The boat is 5727.25ft far from the coast

Given a right ?ABC, where AB = 4.5 cm, BC = 7.794 cm, and AC = 9 cm, sketch the triangle below, and find the measure m?C in degr

Ksju [112]

Answer:

The measure of angle C is $30\°$

The draw in the attached figure

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

In the right triangle ABC

The sine of angle C is equal to divide the opposite side to angle C by the hypotenuse

$sin(C)=\frac{AB}{AC}$

substitute the values

$sin(C)=\frac{4.5}{9}$

$C=arcsin(\frac{4.5}{9})=30\°$
