The measure of an angle is 77 degrees. What is the measure of a supplementary angle?

Two angles are supplementary when they add up to to 180 degrees. Let x be the other angle. 77 + x = 180 x = 180 - 77 x = 103 degrees. So, the required angle is 103 degrees.

The perimeter of the equilateral triangle is 18 cm. Find the length of each side. (Hint equilateral triangle have equal sides.)

Perimeter of the equilateral triangle = 18 cm side 1 = a side 2 = a side 3 = a total perimeter = 18 a + a + a = 18 3a = 18 a = 18/3 a = 6 So, the length of each side is 6cm.

Write an algebraic expression for: eight less than the product of 6 and a number is 5. DO NOT SOLVE FOR X.

Explanation: "Less than" implies that that number will come after what is next. something - 8 "The product of" implies multiplication, and in this case, you would replace "a number" with a value, such as x. (6 times x) - 8 (6x) - 8 The final part, equals, (add the equal sign) (6x) - 8 = 5
