Answer: 25.9</h3>
========================================
x = length of AB
The parallel bases of the trapezoid can be added up, and divided over 2, to get the length of the midsegment. The midsegment is the line that cuts the nonparallel sides (or legs) of the trapezoid in half. The midsegment is parallel to the bases.
So,
(AB+DC)/2 = MN
(x+11.5)/2 = 18.7
x+11.5 = 2*18.7
x+11.5 = 37.4
x= 37.4-11.5
x = 25.9
AB = 25.9
Solution:
Given data:
Let us determine what is h using given A.
Subtract 
on both sides of the expression.
⇒ 
⇒ 
⇒ 
Divide both sides of the expression by 
.
Option C is the correct answer.
Hence .
Answer: B. x=10
Step-by-step explanation:
<u>Concept</u>
- If it is an isosceles triangle, then the altitude would also be the median of the base, meaning that it divides the base evenly.
- We are going to use the Pythagorean theorem which is a²+b²=c², where [a] and [b] are legs, and [c] is the hypotenuse.
<u>Given</u>
Hypotenuse (relative) = √74
Altitude (one leg) = 7
The other leg (half of the base) = x/2
<u>Solve</u>
a² + b² = c²
(7)² + (x/2)² = (√74)²
49 + x²/4 = 74
x²/4 = 25
x² = 100
x = 10

Answer:
∠2 = 41°
Step-by-step explanation:
∠2 + 49° + 90° = 180°
∠2 + 139° = 180°
∠2 = 180° - 139°
∠2 = 41°
