5. Consider adjacent angles that measure (2x + 45) and (3x + 55)'. The sum of the measures of these angles is 135º.
a. Write and solve an equation to find the value of x. SHOW ALL WORK

b. using the value of x, what is the angle measure represented by the expression (2x + 45)?

The length of a rectangle is x times the square root of 100. the width is one-half y more than three-halves x. given that the area of the rectangle is 125 cm2, which equation could represent the rectangle in terms of x and y? a) 5xy − 15x = 125 b) 5xy + 15x = 125 c) 15x2 − 5xy = 125 d) 15x2 + 5xy = 125
