Answer:
x = 16
y = 116
Step-by-step explanation:
Given is a figure of isosceles trapezoid. One pair of opposite sides are parallel and non-parallel sides acts as it's transversals.
Therefore,
4x° + (6x + 20)° = 180° ( interior angles on the same side of transversal)
(6x + 20 + 4x)° = 180°
(10x + 20)° = 180°
10x + 20 = 180
10x = 180 - 20
10x = 160
x = 160/10
x = 16
Measure of base angles of an isosceles trapezoid are equal.
Therefore,
y° = (6x + 20)°
y = 6x + 20
y = 6*16 + 20
y = 96 + 20
y = 116
Answer:
a + b + c + d + e = 180.
Step-by-step explanation:
We can prove that a = angle CBA (vertically opposite angles are equal).
Now, since lines DE and CA are parallel, then it follows that c = angle ACE (alternate angles are equal). Similarly, b = angle CAD.
But notice that what we've just done is found the angles of the triangle CBA.
So the sum of the angles (a + b + c + d + e) is the sum of the angles of a triangle.
We then conclude that a + b + c + d + e = 180 degrees.
Answer:
Principle for account B is greater.
<em></em>
Step-by-step explanation:
First of all, let us have a look at the formula for Simple Interest:
Where 
is the principle amount
is the Rate of interest per annum
is the time in years.
Time = 21 months = 
Let the Principles be 
.
Using the formula for Simple Interest, we get:
Therefore, <em>principle for account B is greater</em>.
