Find the length of CA to the nearest tenth of a foot

hoa [83]

Answer:

CA ≈ 3.1 ft

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan40° = $\frac{opposite}{adjacent}$ = $\frac{BC}{CA}$ = $\frac{2.6}{CA}$ ( multiply both sides by CA )

CA × tan40° = 2.6 ( divide both sides by tan40° )

CA = $\frac{2.6}{tan40}$ ≈ 3.1 ft ( to the nearest tenth )

Use this diagram to find the measures of the lengths of the sides. The perimeter of the trapezoid on the right is 97 inches.

Leya [2.2K]

Answer: 14 in. , 21 in. , 14 in. , and 48 in.

Step-by-step explanation:

Given : The perimeter of the trapezoid = 97 inches

The sides of the trapezoid are x in., 1.5x in. , x in. ,and (3.5x-1) in.

We know that the perimeter of any polygon is the sum of all sides.

Thus, $x+x+1.5x+3.5x-1=97\\\Rightarrow7x=97+1\\\Rightarrow\ 7x=98/\\\Rightarrow\ x=14$

Substitute the value of x in the sides of the trapezoid, we get the sides of trapezoid as

$x\rightarrow14\ in.\\1.5x\rightarrow1.5\times14=21\ in.\\3.5x-1\rightarrow3.5(14)-1=48\ in.$

Hence, the lengths of the sides of the trapezoid are 14 in. , 21 in. , 14 in. , and 48 in.
