Side CB is the same as AD.
Side AB is the same as CD.
<CAD is 15 degrees
<ACD is 24 degrees
now use a^2 +b^2=c^2 to find the last angle

As its given, this is a parallogram Side AB = 12
Side BC = 13

Angle CAD = 15
Angle ACD = 24

Sum of all angle in triangle = 180
Angle ADC = 180 - 15 -24 = 141
Angle ABC = 141

Help please!!! thanks

Answer:

Step-by-step explanation:

first we can simplify by dividing by r

$\frac{9 {r}^{2} }{r} = \frac{9 \times r \times r}{r} = 9 \times r \times 1 = 9r$

the r on the bottom of the fraction will cancel out one of the r's on top, this happens because anything divided by itself is 1, thus r divided by r is 1

finally we can evaluate when r =3,

9r = 9(3) = 27
