Answer:

62 degrees

Step-by-step explanation:

As two sides shown are same in length thus angle containing by them will be also same.

Thus, other unmarked angle will also be x degrees.

one angle is 56 degrees

we know that sum of angle of triangle is 180 degrees.

Thus

x + x + 56 = 180

2x + 56 = 180

2x = 180 - 56 = 124

x = 124/2 = 62

Thus, value of x is 62 degrees.

An art project has an area of 63.6 square inches. What is the width, in inches, of the project?

Flura [38]

Answer:

The width of the art projects of area 63.6 square inches is 7.97 inches .

Step-by-step explanation:

Given as :

The area of the square art project = 63.6 square inches

Since The shape of the art project is square

So, The Area of square = A = side × side = side²

Now, let the measure of the width of art project = w inches

I.e side = w inches

or , A = side²

Or , A = w²

Or, 63.6 = w²

So, w = $\sqrt{63.6}$

I.e w = 7.97 inches

So, the width of the projects = w = 7.97 inches

Hence The width of the art projects of area 63.6 square inches is 7.97 inches . Answer
