Answer:

76

Step-by-step explanation:

A full triangle is 180 *always remember

180-153=27

so r is 27

180-77-27=76

or you could do

77+27+x=180

104+x=180

x=180-104

x=76

Answer:

 1)   Volume of prism = \frac{105}{8}ft^3=13.125ft^3

 2) Option B is the correct answer.

Explanation:

1) Volume of a prism is given by the expression, Volume V = Base area of prism x Height of prism.

 Base area = 3\frac{1}{2} *2\frac{1}{2}=\frac{3*2+1}{2} *\frac{2*2+1}{2} =\frac{7}{2} *\frac{5}{2}=\frac{35}{4} ft^2

Volume = \frac{35}{4}*1\frac{1}{2} =\frac{35}{4}*\frac{1*2+1}{2}=\frac{35}{4}*\frac{3}{2}=\frac{105}{8}ft^3

 Volume of prism = \frac{105}{8}ft^3=13.125ft^3

2) Volume of a prism is given by the expression, Volume V = Base area of prism x Height of prism.

 Base area = 4\frac{1}{4} *3in^2

 Volume = 4\frac{1}{4} *3*1\frac{1}{4}in^3

 Option B is the correct answer.
