Hi, thank you for posting your question here at Brainly.
All you have to do to acquire the equation is to substitute the variables to the formula for A and simplify. Since A = 1/2*b*h and h = bsin(C), then A can be in terms of one variable only, which is b.
A = 1/2*b*bsin(c)
A = 1/2*b^2*sin(C)
Answer:
(6,12)
Step-by-step explanation:
Substitute the value of y into y=2x:
x+6=2x
x=6
Substitute x into the equation of y=2x
y = 2*6 = 12
(6,12)
Answer:
Step-by-step explanation:
Actually, -13 can be classified as any and all of these.
Sum of interior angles of triangle = 180
x + x + 6 + 3x - 16 = 180
5x - 10 = 180
5x = 190
x = 38
<M = 3(38) - 16
<M = 114 - 16
<M = 98°
Answer:
The cosine of the angle is: negative
The sine of the angle is: positive
