Answer:
<6 = 68
Step-by-step explanation:
<5 + <6 + 90 = 180 since the 3 angles form a straight line
22 + <6 + 90 =180
Combine like terms
112+ <6 = 180
Subtract 112 from each side
<6 = 180-112
<6 =68
The side length of Rs is dependent on QRS
2x^2-8x-24=0
Divide the whole equation by 2.
x^2-4x-12=0
Complete the square
x^2-4x+4-16=0
(x-2)^2 -16=0
(x-2)^2=16
Take the square root of each side.
(x-2)=4 and (-(x-2))=4
x=6 and x=-2
