The measures of the angles in a triangle are in the ratio of 2:2:4. Find the exterior angle that is adjacent to the largest angle

90°

Step-by-step explanation:

Let there measures of the angles of a triangle are 2x, 2x and 4x.

We know that the sum of angles of a triangle is equal to 180°. So,

2x+2x+4x=180

8x=180

x = 22.5

We know that, the measure of an exterior angle of a triangle is equal to the sum of the measures of the two non-adjacent interior angles.

So, the exterior angle = 4x = 4(22.5) = 90°

wholesale price is the initial price before markup. retail price comes after the markup.

a price of 8 bucks that's marked up by 100%   is

formula: initial price + (percent markup in fraction/decimal)(initial price)

8+(1)(8)

8+8

16

retail price is $16.
