x = 85 degrees and

y = 45 degrees.

Step-by-step explanation:

Step 1:

The angle for a straight line is 180°. The sum of the angles in a triangle is 180°. These two statements are required to solve this problem.

The angles of x° and 95° are on a single straight line.

So $x^{\circ} + 95^{\circ} = 180^{\circ}.$

$x^{\circ} = 180^{\circ} - 95^{\circ} = 85^{\circ} .$

So the angle of x is 85°.

Step 2:

The sum of the angles in a triangle is 180°.

So $50^{\circ} + x^{\circ} + y^{\circ} =180^{\circ}.$

$50^{\circ} + 85^{\circ} + y^{\circ} =180^{\circ}.$

$y^{\circ} =180^{\circ} - 135^{\circ}, y = 45 ^{\circ}.$

So the angle of y is 45°.

How to calulate the area of a square with a perimeter of 60 inches

olasank [31]

Answer:

Step-by-step explanation:

The formula of an area of a square:

$A=s^2$

s - side

The formula of a perimeter of a square:

$P=4s$

s - side

We have a perimeter

$P=60\ in$

Substitute:

$4s=60$ divide both sides by 4

$\dfrac{4s}{4}=\dfrac{60}{4}\\\\s=15\ in$

Put it to the formula of an area of a square:

$A=15^2=225\ in^2$
