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.

Step-by-step explanation:
we have
<em>Find the x-intercept</em>
Remember that the x-intercept is the value of x when the value of y is equal to zero
For y=0
the x-intercept is the point (2,0)
<em>Find the y-intercept</em>
Remember that the y-intercept is the value of y when the value of x is equal to zero
For x=0
the y-intercept is the point (0,-5)
