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:
because 1+1 adds up to 2
Step-by-step explanation:
To find the mean, add the numbers, and divide by the amount of numbers there is.
(82 + 105 + 247 + 119 + 94 + 202)/6
Simplify. Remember to follow PEMDAS. First, add
(849)/6
Next, divide by 6
849/6 = 141.5
141.5 should be your answer
