answer:

63 inches squared

step-by-step explanation:

  • in order to find the area of just the shaded portion, we would have to subtract the not shaded portion from the whole rectangle
  • first, find the area of the whole rectangle

1 ft = 12 inches (conversion)

12 X 6 = 72 in^2 (area of the whole rectangle)

  • now, find the area of the not shaded portion

3 X 3 = 9 in^2 (area of the not shaded portion)

  • so, now that we have both areas, we just have to subtract them to find the area of the shaded portion

72 - 9 = 63

- - > 63 inches squared

A triangle has a height of 15 in. and a area of 120 in. What is the length of it's base?
jek_recluse [69]

Answer:

b=16

Step-by-step explanation:

Formula~ 1/2*b*h

1/2*15*b=120

7.5b=120

b=120/7.5

b=16

(you can substitute the value to check-i've done it below)

1/2*16*15=?

if you work it out, the ans will be 120, therefore the ans is correct!

BAC ~ DEC what is the value of x?
Anna007 [38]

Answer: x = 37.8

Step-by-step explanation: We start with triangle ABC with two sides given as 15 and 18. We shall make angle C the reference angle and thereby calculate the third side, line BC.

Since we have the opposite side as 15, and the adjacent side (which lies between the reference angle and the right angle) as 18, we can use the tangent of the angle C

Tan C = Opp/Adj

Tan C = 15/18

Tan C = 0.8333

From our table of values/use of the calculator

Tan C = 39.8

Angle C in triangle ACB = Angle C in triangle ECD (Opposite angles are equal).

That takes us to triangle ECD, since the reference angle is known (39.8) and the opposite side is also given (31.5), we can now calculate the adjacent which is side x.

Tan C = Opp/Adj

Tan 39.8 = 31.5/x

when you cross multiply, x moves to the left hand side, while Tan 39.8 moves to the right hand side

x = 31.5/Tan 39.8

x = 31.5/0.8333

<u>x = 37.8</u>
