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°

518,400

step-by-step explanation:

the area is multiplying all the given measurements together.

40 * 18 * 30 * 24 = 518,400
