Answer:
=19.81 in²
Step-by-step explanation:
We use the sine formula to find the area of the triangle in question.
In this formula we find the product of two adjoined sides with the sine of the angle between them.
The sides b and c are bound by the angle A.
Therefore area=1/2bcSin A
A=1/2×13.2 in×5.3 in× Sin 34.5
=19.81 in²
-7
Step-by-step explanation:
First, set the equation equal to one and the x's to 2
Then, solve the parts without variables
4(2)+a(2)+6(2)-5=1
8+a(2)+6(2)-5=1
8+a(2)+12-5=1
Then add like terms
8+a(2)+7=1
15+a(2)=1
Then subtract 15 from both sides
a(2)=-14
Finally, divide by two on both sides
a=-7

Answer:
3.69 hours
Step-by-step explanation:
y = 80.25x + 78.75
y = 95.75 + 40
85.25x + 78.75 = 95.75 + 40
-85.25x -40 -85.25x -40
38.75/10.5 = 10.5x/10.5
3.690476190..... = x
rounding
3.69 = x
