A quadrilateral has twi angels that measure 150 degrees and 50 degrees. The other two angles are in a ratio of 3:5. What are the measures of these two angles

Quadrilateral angles sum up to 360

The two angles when sum up will be

The other two angles when sum up will be

This angle 160 is shared in the ratio 3:5

We will add the two ratios up which will be

To get one angle we will divide 3 by 8 n multiple the results by 160 . this will be

The other angle can be solve in two ways

First approach

160-60=100

Second Approach

Using the earlier method

The two angles are 60 and 100

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)
