Answer:
Step-by-step explanation:
Since, we have to change
inches / sec to feet/ min
It means that
we have to change
inches to feet
and sec to min
we know that
and
so, we will use these two factors only
Answer:
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.
Answer:
X = 38°
