Step-by-step explanation:
Answer:
x = 59°
Step-by-step explanation:
The angle marked 115° and the angle that is the sum of angles x and 56° are alternate interior angles, so have the same measure:
115° = x +56°
59° = x . . . . . . . subtract 56°
Answer:
If x=8 then the equation is equal to 33
If 1/2(x)^2-1/4x=3=8 then x=-2.98 and x=3.35
Step-by-step explanation:
Given:
1/2x^2-1/4x+3
Two solutions possible:
If x=8 then 1/2(8)^2-1/4(8)+3=32-2=3=33
If 1/2(x)^2-1/4x+3=8 then .5x^2-.25x-5=0
factoring:
(.707x+2.11)(.707x-2.37)=0
.707x=-2.11 and .707x=2.37
x=-2.98 and x=3.35 rounded to 2 places
