Answer:
2
Step-by-step explanation:
If the equation is in the form y = mx + b, then m is the slope and b is the y-intercept (For example - in the equation y = 3x + 2 the slope is 3 and the y-intercept is 2)
In this case, the number next to x is 2, so that's the slope.
Use the sine rule.
For any triangle: sin(a) / A = sin(b) / B = sin(c) /C
Where A is the side opposed to angle a, B is the side opposed to angle b, and C is the side opposed to angle c.
Here, sin(B) / AC = sin(A) / BC = sin (C) / AB
<span> BC = 12.35, AC = 8.75 centimeters, and m∠B = 37°
sin(37) / 8.75 = sin(A) / 12.35 => sin (A) = 12.35 * sin(37) / 8.75
sin(A) = 0.845 = A = arctan(0.845) = 58.15°
And A + B + C = 180° => C = 180 - A - B = 180 - 58.15 - 37 = 84.85
Answer:
measure of angle A = 58.15°
measure of angle C = 84.85 °

Step-by-step explanation:
√(1 - cos^2x) = sin x
and
√(1 - sin^2x) = cos x
So the expression becomes:
sin x / sin x + cos x / cos x
= 2

Answer:
60 hand shakes.
Step-by-step explanation:
We have been given that there are 6 married couples at a party.
This means there are 12 people in total.
We know that number of handshakes for n people is given by formula 
.
We are also told that at the start of the party every person shakes hands once with every other person except his or her spouse.
So formula for this problem would be 
or 
.
Since total numbers of people is party is 12, so we will get:
Therefore, there will be 60 hand shakes at the party.
