The total measure of the interior angles of a quadrilateral is 360 degrees
you are given 57, 65, 118
That is 240
to solve for the last angle
360-240
120
The exterior angle of a D would be the number that you add that will make it 180 degrees.
meaning 180-120 is
The exterior angle of angle D is 60 degrees.
Hope this helps
P=18
Angle e and c are the same because they are opposite interior angles. Therefore you can set it up in an equation like: 117=5P+27 and solve.
117=5P+27 you need to subtract 27 from both sides
90=5P you need to divide both sides by 5 to get
P=18
Answer:
23/7
Step-by-step explanation:
7x + 15 = 38
subtract 15 from both sides : 7x+15-15=38-15
7x=23
divide both sides by 7: 7x/7 = 23/7
x=23/7
For Ramona to know how much she expects to pay for the carpet she is ordering, she first needs to know how many square foot the the room has.
In getting the area of the room, you multiply one side with the other,
in equation,
19.5 ft x 41.6 ft = 811.2 sq ft.
Then if the carpet costs $9.50 per sq ft, you simply multiply it the area of the room
in equation,
$9.50/ sq ft. x 811.2 sq ft, cancelling out the unit of sq ft
the answer would be $7,706.4
