Answer: x = 37.8
Step-by-step explanation: We start with triangle ABC with two sides given as 15 and 18. We shall make angle C the reference angle and thereby calculate the third side, line BC.
Since we have the opposite side as 15, and the adjacent side (which lies between the reference angle and the right angle) as 18, we can use the tangent of the angle C
Tan C = Opp/Adj
Tan C = 15/18
Tan C = 0.8333
From our table of values/use of the calculator
Tan C = 39.8
Angle C in triangle ACB = Angle C in triangle ECD (Opposite angles are equal).
That takes us to triangle ECD, since the reference angle is known (39.8) and the opposite side is also given (31.5), we can now calculate the adjacent which is side x.
Tan C = Opp/Adj
Tan 39.8 = 31.5/x
when you cross multiply, x moves to the left hand side, while Tan 39.8 moves to the right hand side
x = 31.5/Tan 39.8
x = 31.5/0.8333
<u>x = 37.8</u>
Answer:
6+3-8-7 = 8
1+4+10-8 = 7
3-3+9+1 = 10
10-2+10-8 = 10
2+0+1+2+3 = 8
10-1-2-3+4 = 8

i don't know if these are supposed to be easy or not lol but thanks for the points :p

m is 5 and k is 0
Hi,
Answer: All Real Numbers
This can be achieved in 7 easy steps!
<u>My Numerical work:</u>
1. 2p + 3 > 2(p - 3)
Simplify both sides of the inequality:
2. 2p + 3 > 2p - 6
Subtract 2p from both sides:
3. 20 +3 - 20> 2p - 6 - 2p
4. 3 > -6
Subtract 3 from both sides:
5. 3 -3 > -6 - 2p
6. 0 > -9
7. All real numbers are solutions.
I Hope I Helped!
The slope intercept form is y = mx + b.
The first thing we have to do here is move the term with the x variable over to the right side of the equation.
-2x + 5y = -15 And we do that by adding 2x to both sides of the equation.
5y = 2x - 15
We then have to get y alone. So we divide 5 on both sides.
The answer is y = 2/5x - 3
