Step-by-step explanation:
824 - 764 = 60 / 10 = 6
Answer:
A = 56 in²
Step-by-step explanation:
the area (A) of a trapezoid is calculated as
A = h (b₁ + b₂ )
h is the perpendicular height between bases and b₁, b₂ the bases
here h = 7 , b₁ = 10 , b₂ = 6 , then
A = × 7 × (10 + 6) = 3.5 × 16 = 56 in²
Answer:
The answer is 120
Step-by-step explanation:
First let's find the angles a and b.
We have then:
sin a = 4/5
a = Asin (4/5)
a = 53.13 degrees.
cos b = 5/13
b = Acos5 / 13
b = 67.38 degrees.
We now calculate cos (a + b). To do this, we replace the previously found values:
cos ((53.13) + (67.38)) = - 0.507688738
Answer:
-0.507688738
Note: there is another way to solve the problem using trigonometric identities.
