Answer:
116°
Step-by-step explanation:
(there are 2 right angles) 
90 + 90 = 180
180 + 64 = 244
(a quadrilateral adds up to 360°)
360 - 244 = 116

Answer:
He multiplied the denominators incorrectly
Step-by-step explanation:
we know that
The volume of a rectangular prism is given by the formula
V=LWH
we have
L=3/4 ft
W=5/1 ft
H=1/2
substitute
V=(3/4)(5/1)(1/2)= 3x5x1=    15
                            ₋₋₋₋₋₋₋₋    ₋₋₋₋ ft³
                            4x1x2=    8
                        
therefore
He multiplied the denominators incorrectly
 
        
             
        
        
        
Answer: 39.22 yd^2 (as in yards squared)
Step-by-step explanation: 
1. DO NOT FOCUS ON THE 6! JUST FOCUS ON THE BASE AND HEIGHT!
2. Area= b*h
3. Plus in your numbers. Area=3.7*10.6.
4. Multiply. Area=39.22 yds^2
 
        
             
        
        
        
12,176/24 = 1522/3 or 507 1/3
