30 degrees. A triangle is 180. The right angle is 90.
90=7x-10+3x
add ten to both sides and combine like terms
100=10x simplify
10=x now substitute
3x
3(10)=30

Step-by-step explanation:

step 1

Find the surface area of the cylinder

The surface area of the cylinder is equal to

$SA=\pi r^{2} +2\pi rh$

we have

$r=3/2=1.5\ in$ ----> the radius is half the diameter

$h=5\ in$

assume

$\pi =3.14$

substitute

$SA=(3.14)(1.5)^{2} +2(3.14)(1.5)(5)=54.165\ in^{2}$

<em>Find the cost</em>

$54.165*(0.75)=\$40.62$

step 2

Find the surface area of the square prism

The surface area of the prism is equal to

$SA=b^{2} +4bh$

we have

$b=3\ in$

$h=5\ in$

substitute

$SA=(3)^{2} +4(3)(5)=69\ in^{2}$

<em>Find the cost</em>

$69*(0.75)=\$51.75$

step 3

Find the difference of costs

$\$51.75-\$40.62=\$11.13$
