Answer:
120
Step-by-step explanation:
The sum of the degrees in any quadrilateral is 360. So add up all of the degrees you know and subtract it from 360 to get your answer.
120 + 60 + 60 = 240
360 - 240 = 120
another way you know that's easier is the angles that are diagonal are equal to one another, so since x is diagonal to 120, it is equal to 120.
c+2
Distribute the Negative Sign:
=9c2+3c+9+−1(9c2+2c+7)
=9c2+3c+9+−1(9c2)+−1(2c)+(−1)(7)
=9c2+3c+9+−9c2+−2c+−7
Combine Like Terms:
=(9c2+−9c2)+(3c+−2c)+(9+−7)
V = πr²h
V = 3.14 (5cm)²(7 cm)
V = 3.14 (25cm²) ( 7 cm)
V = 3.14 (175 cm³)
V = 549.50 cm³
