Answer:

x=8

Step-by-step explanation:

so since the whole thing should equal 180, and the right triangle is 90,

(3x+11)+(5x+15)=90 then solve for that

8x+26=90

8x=64

divide both sides by 8

so x=8

then plug in 8 for the xs so c is 3(8)+11 --> 24+11 so m<C=35*

m<D=90*

5(8)+15 40+15 so m<E=55

skelet666 [1.2K]

The store sells a product for 40% more than the what they buy it for.
40% is 0.40 in decimal because all percents are out of 100 (divide by 100)
300×(1+0.40)=$420
