Answer:
<h2>D. 13</h2>
Step-by-step explanation:
Remember that in a isosceles trapezoid, its angles on the base are always congruent.
Also, we know by definition that the sum of interior angles of a trapezoid is equal to 360°, so
Therefore, the right answer is D.
5x + 10 10
---------- = -------
121 11
make the bottom have same common denominator
10/11 x (10/10) = 100/121
Get rid of the denominator (for both now have 121 as a base)
5x + 10 = 100
5x + 10 (-10) = 100 (-10)
5x = 90
5x/5 = 90/5
x = 18
x = 18 is your answer
hope this helps
Boy: x
girl: x - 53
father: 4(x - 53)
Now you simplify.
Answer:
s = 15
Step-by-step explanation:
We know that a straight line measures 180°
so… in order to find the value of s add the two angles with a sum of 180 and then solve for s
(9s + 8)° + 37° = 180°
Combine like terms
9s + 45 = 180
Subtract 45 from both sides
9s = 135
Solve for s
s = 135/9
s = 15
