Best Answer

the angle in a rectangle is 90 degress

angles in a equilateral triangle is 60 degree each.

in this question they usually give you the triangle at an angle and give you what the angle is. so if you add them together they should all add to 90 degrees.

so basically the trick is in what type of triangle it is.

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

How is perimeter and area related in a rectangle?

The perimeter of a rectangle is the distance around the rectangle. The area of a rectangle is the space inside the rectangle. To calculate either one you need the length and the width of the rectangle. To calculate the area multiply the length times the width. To calculate the perimeter add the length+width+length+width (that is the distance all the way around)

How do you calculate the area of on incomplete rectangle?

It is not clear what you mean by an incomplete rectangle. If it means the rectangle is not closed then there is a problem of defining its area: what is inside and what is outside when you do not have a boundary?

The perimeter of a rectangle is 22 ft a right triangle inside the rectangle has a perimeter of 12 ft it's hypotenuse is 5 ft one side of the triangle is half the length of the rect solve all length?

ok, i figured it out. the length of the triangle is 5, 4, 3. the four is 1/2 the length of one side of the rectangle. so the rectangle sides are 8, 8, 3, 3 (one three being one side of the rectangle as well)
