I have attached an image of the right trapezoid.
Answer:
C: 107°
Step-by-step explanation:
From the image attached, we can see that the right trapezoid has 2 internal angles which are right angles while it has a third angle which is 73°.
Now,we want to find angle WXY.
Sum of angles in a trapezoid is 360°.
Thus;
90 + 90 + 73 + ∠WXY = 360
253 + ∠WXY = 360
∠WXY = 360 - 253
∠WXY = 107°
X(7-x)>8 perform indicated multiplication on left side
7x-x^2>8 divide both sides by -1
x^2-7x<-8 halve the linear coefficient, square it, and add it to both side ie (-7/2)^2=12.25
x^2-7x+12.25<4.25 now the left side is a perfect square
(x-3.5)^2<4.25 take the square root of both sides
x-3.5<±√4.25 add 3.5 to both sides
x<3.5±√4.25
So x>3.5-√4.25 and x<3.5+√4.25 or if you want approximations
x>1.44 and x<5.56 or in interval notation:
x=(1.44, 5.56) (to nearest hundredths)
Answer:
$75
Step-by-step explanation:
25*3
To solve for x, simply rearrange the problem:
