The area of a rectangle is 84 cm and the length is 5 more than the width. find the length and width

Step-by-step explanation:

Area = length x width

let x represent the width of the rectangle

therefore

however since length cannot be negative, the width is 7.

width = 7

length = 7+5

= 12

step-by-step explanation:

just plug in each number for x and see which ones work and don't

a. 74 degrees

step-by-step explanation:

because the lines through the side and the box in the corners shows that these are congruent triangles and since they are mirrored the 37 degrees is also mirrored so the answer is 37 * 2 which is 74.
