Answer:
One half (1/2) the measurement of the third side
Step-by-step explanation:
Mid segment theorem defines the relationship between the constructed line joining the midpoint of two sides of a triangle, and parallel to the third side of the triangle which is also called the midsegment
Whereby the angles are defined by the proportion of the sides, the midsegment will have a length which is half the measurement of the length of the third side.

Answer:
Step-by-step explanation:
Let 'a' and 'e' represent Alvin's and Elga's ages, respectively.
a = e-12 . . . . . Alvin is 12 years younger
a + e = 86 . . . the sum of their ages is 86
__
Substituting for 'a' gives ...
(e -12) +e = 86
2e = 98
e = 49
a = 49 -12 = 37
Alvin is 37; Elga is 49.
Whenever you're interested in computing the (absolute) difference between two values of a certain variable, you have to subtract the final value and the initial value. This is often written as delta:

So, in this case, the final temperature is -30°F. The initial temperature is 115°F. So, the variation is

A negative delta indicates that the value decreased, which is our case.
Answer:
3.1
Step-by-step explanation:
It is 45 because angle EBC is congruent to CDE (x) because of a rule called alternate angles. so x= 45°
