Answer:

y = 12 degrees

x = 40 degrees

Step-by-step explanation:

Triangle BDE: 3y + 54 + 90 = 180

3y + 144 = 180

3y = 36

y = 12

Line AC: angles on a straight line = 180

116 + 54 = 170

so, angle EBC = 10

Triangle BCE: 10 + 90 + 2x = 180

100 + 2x = 180

2x = 80

x = 40

To find the x-intercepts algebraically, we let y = 0 y=0 y=0 in the equation and then solve for values of x. In the same manner, to find for y-intercepts algebraically, we let x = 0 x=0 x=0 in the equation and then solve for y.

Someone please tell me what to do

For this, we need to find the area of the larger rectangle (The room) and subtract from that the area of the smaller, shaded rectangle (The rug).
A=LW (L=Length, W=Width, A=Area)

The larger rectangle first:
A=(15)(10)
A=150 feet squared

Now the Rug:
A=(12)(7)
A=84 feet squared

Now to find the area that is NOT covered by the rug, we subtract:
150-84
= 66 feet squared will NOT be covered by the rug.

Hope this Helps!
