To find X set up a ratio of the two top dimensions and the two bottom dimensions first:

5/3 = 40/2x +10

Now cross multiply:

5 * 2x+10 = 3*40

Simplify:

10x +50 = 120

Subtract 50 from each side:

10x = 70

Divide each side by 10:

x = 70/10

x = 7

The area of a right triangle with one leg measuring 5 ft. and hypotenuse measuring 13 ft. is_______ a0. Type a numerical answer
Snowcat [4.5K]

Area of the triangle = (1/2)*base*height

For right triangle base and height can be legs.

We have one leg = 5 ft. (Lets think it is a base.)


We need to find the other leg.

We are going to use Pythagorean theorem.

5² + b²=13²

b²=144

b=12 (It is going to be our height.)


Area of the triangle = (1/2)*5*12= 30 ft²

Area of the triangle = 30 ft²

Answer:

Circumference is 18.84 feet. Area is 28.26 square feet.

Step-by-step explanation:

Given:

Radius of the circle, r=3\textrm{ ft}

The value of \pi is 3.14.

Now, circumference of a circle of radius r=3 is given as:

Circumference=2\pi r=2\times 3.14\times 3=18.84\textrm{ ft}

Also, area of the circle of radius r=3 is given as:

Area=\pi r^{2}=3.14\times (3)^{2}=3.14\times 3\times 3=28.26\textrm{ }ft^{2}

Therefore, the circumference of the circle is 18.84 feet and area of the circle is 28.26 square feet.

An isosceles trapezoid has base angles of 45° and bases of lengths 9 and 15. The area of the trapezoid is 36 sq. units 72 sq. un
Butoxors [25]

Answer:

Area = 36 sq units

Step-by-step explanation:

An isosceles trapezoid have two triangles and probably a rectangle or a square.

To find the area, let's determine the height of the trapezoid.

The base length of one of the triangle

= (15-9))2

= 6/2 = 3

The height will be x

X /sin 45= 3 / sin 45

X= 3

The area of the trapezoid

= 1/2(a+b)h

Where a = 15

b = 9

h = 3

Area= 1/2(15+9)3

Area= 1/2 *24*3

Area= 12*3

Area = 36 sq units
