Given cos theta is equal to - 4/ 7 then we can conclude that theta is in the second and third quadrants. In this case, the other leg is equal to square root of (7^2 - 4^2 ) equal to square root of 33. In this case, sin theta can be equal to +- square root of 33 / 7 and tan theta is equal to +-square root of 33 / 4.
Basically you substitute 16 in for x.
f(16) = 3/4(16) - 5
f(16) = 12 - 5
f(16) = 7
The area is 128 inches squared.
Step-by-step explanation:
12 times 8 is 96, plus the two side triangles (32 when combined) is 128.
Answer:
56
Step-by-step explanation:
x+x+8=104
2x=96
x=48
48+8=56
