The interior angles of a triangle equal 180°. To find y you do 180°-57-61 which equals 62. So the measure of angle y is 62°. You add 62 and 67 to get 129. Then you do 180 - 129 = 51. So the measure of angle x is 51°
Each of them is correct as they all found the area of the base and then multiplied it be the height. I personally would have done the third option because I like having all the items written out.
A. N=6 would be the answer
The variable we need to isolate is P. In order to do so, we add a / 3w on both sides.
P =
