Answer:
$134,820
Step-by-step explanation:
is the correct answer
When we need the cosine of the sum of two angles, we use the addition formula for cosine.
When we need the sine of the difference of two angles, we use the difference formula for sine.
Let's try one. Say we needed to know

We're only expected to know the trig functions of 30/60/90 and 45/45/90 triangles. Fortunately,

so



Answer:
C is the correct option
Step-by-step explanation:
To find the probability of P(a or b) we will use the formula:
P(a or b)= P(a)+ P(b) - P(a-b)
Now put the given values in the formula:
P(a or b)= 0.60+0.25-0.15
P(a or b)=0.85 - 0.15
P(a or b)= 0.70
Thus the correct option is C....
