Answer:
19cm
Step-by-step explanation:
The area of a trapezoid (where a and b are the parallel sides).
Given:
Area = 189 Square cm
Height, h=14cm
a=8cm
We want to find the value of the other parallel side, b.
Substitution of the given values gives:
The length of the second parallel side is 19cm.
Answer:
A. V= area of base x height 1/3
(20x15)x30x1/3= 3000cm
B.65cm
C.CTCN is the angle between
tan<TCN= TN/NC=12/5
=67.380
D. 10\sqrt(10)
e.tan<TMN=TN/MN=3
<TMN=71.57
Answer:
$5 an hour
Step-by-step explanation:
Set up your equation like this: 40x+50=250
Then solve for x
First, subtract 50 from 250, leaving you with 200.
Then divide 200 by 40, and you get 5.
The side opposite the right angle.
Answer:
ΔABC is a isosceles triangle at A
=> ∠BAC = 180 - 2.∠ABC = 180 - 2.65 = 50°
because AB//CD => x = ∠BAC = 50°
