Answer:
13.4 feet squared
Step-by-step explanation:
Just took the test on edge
We will use the formula:
Area = 1/2*a*c*sinB
where a and c are the length of the sides and B is the angle between those 2 sides
Area = 1/2*5*8*sin42
Area = 20*sin42
sin 42 = <span>0.669130606359
Area = </span>13.38261212718
Rounded to the nearest tenth Area is equal to 13.4

Answer:
x = 114°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles, thus
x + 18° = 132° ( subtract 18° from both sides )
x = 114°
Answer:
17w+35
Step-by-step explanation:
(2+2w)⋅4+9(w+3)
Distribute the 4 and the 9
2*4 + 2w*4 +9*w+9*3
8+8w +9w +27
Combine like terms
8w+9w +8+27
17w +35
