Answer:</h3>
<h3>
Step-by-step explanation:</h3>
If the trapezoid is isosceles, angles A and C are supplementary, so ...
... (4x+4) +(7x+11) = 180
... 11x +15 = 180 . . . . . . collect terms
... 11x = 165 . . . . . . . . . subtract 15
... x = 15 . . . . . . . . . . . . divide by the coefficient of x
And angles C and E are congruent.
... 4·15 +4 = 21y +1
... 63 = 21y . . . . . subtract 1
... 3 = y . . . . . . . . divide by the coefficient of y
Answer:
x = 6
Step-by-step explanation:
Verticle angles are formed when two lines intersect. The angles opposite each other are congruent, those angles are called vertical angles.
Using this knowledge, one can say;
3x + 2= 20
Use inverse oeprations to solve for "x"
3x + 2 = 20
-2 -2
3x = 18
/3 /3
x = 6
Answer:
24:5
Step-by-step explanation:
4 yards is 3 feet, so 4*3=12. There are 12 inches in a foot, so 12*12=144. 144:30= 72:15 = 24:5
