Midsegment of a trapezoid find x​

x = 7

Step-by-step explanation:

Based on the midsegment theorem of a trapezoid, thus:

NP = (JK + ML)/2

Substitute

45 = (3x + 11 + 10x - 12)/2

2*45 = 13x - 1

90 = 13x - 1

90 + 1 = 13x

91 = 13x

Divide both sides by 13

91/13 = x

7 = x

x = 7

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.

all group life insurance is term insurance. actually it is annual renewable term and it is rated on the average age and claims experience of the entire group, which is called "experience rating." remember, this type of insurance has a 31-day grace period and is convertible to whole life upon leaving employment. a contributory group plan requires that both the employer and the employees pay part of the premium. at least 75% of those eligible must participate, so the group is sure to get most of the healthy employees as well as those that are sick.
