Help with this plz, actual answers only plzzz

x = 16   and the measure of angle is 59°.

Step-by-step explanation:

Complementary angles add up to 90 degrees. Meaning that, if you  add the two angles together and add them to equal 90 you can solve for x.

(x + 15) + (3x + 11) = 90       First combine like terms.

4x + 26 = 90   Subtract 26 from both sides.

    -26     -26

4x = 64

x = 16    

If x is equal to 16, then we can find the measure of angle N by inputting the value of x into the expression for the measure of angle N.

m∠N = 3(16) + 11  

m∠N = 48 + 11

m∠N = 59

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm

x=0
