Answer: Only one unique triangle Khaleem could draw that fit these dimensions.

Step-by-step explanation:

Let ABC be a triangle with side-lengths  5 cm, 8 cm, and 7 cm.

Suppose there is another triangle with same side lengths.

Then by SSS congruence criteria both triangles are congruent or exactly equal.

Therefore, if Khaleem wanted to draw a triangle where the sides measured 5 cm, 8 cm, and 7 cm, then only one unique triangle Khaleem could draw that fit these dimensions.

Murrr4er [49]
In fractions they had won 11/20 games. Then if you convert the fraction to a percent you would get 55% after multipling by 5/5 to get the denominator of 100.

The answer would be 55%.

A circle with radius of \greenD{3\,\text{cm}}3cmstart color #1fab54, 3, start text, c, m, end text, end color #1fab54 sits insid
Zolol [24]

Answer:

The area of the shaded region is 125.664 square centimetre

Step-by-step explanation:

Area of the shaded region  =  area of the circle with radius 7 cm - area of the circle with  radius 3 cm----------------(1)

<u>Step 1:  Finding the area of the circle with radius 7 cm</u>

Area of the circle A = \pi r^2

On substituting the value of the radius, we get

Area of the circle A =\pi(7)^2

Area of the circle A = 49 \pi square centimetre----------------(2)

<u>Step 2:  Finding the area of the circle with radius 3 cm</u>

Area of the circle a = \pi r^2

On substituting the value of the radius, we get

Area of the circle a  = \pi (3)^2

Area of the circle a  = 9 \pi square centimetre ----------------(3)

<u>Step 3:  Finding the area of the shaded region</u>

Area of the shaded region  = 49 \pi - 9\pi

= 40 \pi

= 125.664 square centimetre
