<span>Given ratio between the base angle and vertical angle of an isosceles traingle is 2:5
⇒ base angle / vertical angle = 2 / 5
let base angle = x
⇒ verticle angle = (5/2)x
we know that
verticle angle + base angle + base angle = 180°
⇒ ( 5/2 + 1 + 1 ) x = 180°
⇒ (9/2)x = 180°
⇒ x = ( 180° x 2) / 9
⇒ x = 40°
verticle angle = (5/2) x 40° = 100°

<h3>Examples</h3>
(1) If someone bought five DVD players and ten cordless telephones, the equation ((75)(5)+(30)(10)≥255) would be true.
(2) If the electronic store had a parcticularly bad day and they sold two DVD players and one cordless telephone, the equation ((75)(2)+(30)(1)≥255) would be false.

The key to this problem is ignoring all the information that you don't need. You really don't care about the coordinates for T, U, or V. Just W is all that matters. So make a graph, label the X and Y axis, and put a point at (1,5). Now simply turn the entire paper clockwise 90 degrees. If you do this, you'll see that what was the X axis is now the Y axis. And what was the Y axis is now the X axis. Label the axis again, and read the location of the point you marked. If you do so, you'll see that you have to go 5 spaces along the X axis, hence the 5. And you'll go 1 space down on the Y axis, hence the -1.
So the coordinates of W(1,5) rotated 90 degrees clockwise around (0,0) changes to (5,-1).</span>

Answer:
Step-by-step explanation:
Divide 8 1/4 by 6 7/8 and the answer will be 1.2 times heavier.
8 1/4 is 8.25 and 6 7/8 is 6.875 in decimal point and again:
8.25 divided by 6.875 is 1.2.
