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)?

go on the tube you might find some information there

it’s supposed to be -4+45=41

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
