How many times does 40 go into 100 2 1/2 so multiply 23 by 2 1/2 to get 57.5 enjoy
Answer:
Step-by-step explanation:
First you need the third angle (C).
<C + 89 + 45 = 180 All triangles = 180 degrees. Combine the left terms.
<C + 134 = 180 Subtract 134 from both sides
<C = 180 - 134
<C = 46
Next, Let BA = x
x/Sin(46) = 15/Sin(89)
x = 15*sin(46) / Sin(89)
Sin(46) = 0.7193
Sin(89) = 0.9998
x = 0.7193 * 15 / 0.9998
x = 10.7911
Note
When you are studying this material, you should note 2 things.
- The first is that you are dealing with 2 ratios that are equal to each other.
- The second is, the side is always opposite the angle in the triangle. The two are connect. Side c = 15. It is opposite the 89o angle.
Answer:
(0,-5)
(4,-2)
(-16,-17)
Step-by-step explanation:
Any (x,y) point that satisfies the equation is a solution. First simplify the equation.
3x - 4y - 8 = 12
3x - 4y = 20
Substitute x = 0 and y = -5.
The equation becomes 3(0) -4(-5) = 20.
0 + 20 = 20
This is a solution.
The following points also work and are solutions.
(4, -2) and (-16,-17)
Answer:
m<1 = 57
Step-by-step explanation:
they are vertical angles
Answer:
8 =x
Step-by-step explanation:
2x+9=3x+1
Subtract 2x from each side
2x-2x+9=3x-2x+1
9 = x+1
Subtract 1 from each side
9-1 = x+1-1
8 =x
