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.
The coordinates of Δxyz ⇒⇒ x(1,1) y(2,3) z(3,2)
The coordinates of Δx'y'z' ⇒⇒ x'(2,-2) y'(4,2) z'(6,0)
1. Applying the transformation of the first sentence on Δxyz
The results are ⇒⇒⇒ (2,-2) (4,2) (6,0)
2. Applying the transformation of the second sentence on Δxyz
The results are ⇒⇒⇒ (12,14) (24,38) (36,28)
3. Applying the transformation of the third sentence on Δxyz
The results are ⇒⇒⇒ (12,-36) (24,-12) (36,-24)
4. Applying the transformation of the fourth sentence on Δxyz
The results are ⇒⇒⇒ (2,-6) (4,-2) (6,-4)
By comparing the results obtained with the coordinates of Δx'y'z'
So, the correct answer is the first sentence.
<span>dilation with respect to the origin by a scale factor of 2 followed by a translation of 4 units down</span>
Answer:
Step-by-step explanation:
A proportion is being directly related to something, meaning that there is just multiplication or division (just a coefficient in front of the x-coordinate, nothing more).
In a graph, a proportional graph is a graph that goes straight through the origin.
