Answer:
Option A is correct.
Step-by-step explanation:
Given an isosceles trapezoid has base angles of 45° and bases of lengths 8 and 14. we have to find the area of isosceles trapezoid.
An isosceles trapezoid has base angles of 45° and bases of lengths 8 and 14.
From the figure attached , we can see an isosceles trapezoid ABCD,
AB = 8cm and CD=14cm
So we have to find the value of AE which is the height of Trapezoid in order to find area.
In ΔAED
⇒
∴ AE = DE =3cm
h=3cm, a=14cm, b=8cm
hence,
Option A is correct.
X+(x+2)+(x+4)+(x+6)=80
4x+12=80
4x=68
x=17
the numbers are 17,19,21,23
Answer:
6
Step-by-step explanation:
Okay so we set up a proportion:
To solve this, we need to cross multiply to find x. And x symbolizes the cups of sugar.
So 2 x 21 = 42
42 divided by 7 = 6
So the answer is 6.
When you combine like terms you get 2y+2x+2 so and for letter A when you distribute you get the same so Letter A is correct.
