How do I find the unknown angles?

Mathematics
1 answer:
Svet_ta [14]3 years ago
4 0

so 1 and 2 are supplementary, meaning that they add up to 180. so 1 is 180-45, which is 135.

3 is a vertical angle to 1, so 1 and 3 are the same. that means that 3 is also 135


Answer:

m<1=135°

m<3=135°

satela [25.4K]

Answer:

To dilate the figure by a factor of 2, I will multiply the x and y-value of each point by 2. I plotted all the new points to find the new triangle. To dilate the figure by a factor of 2, I will multiply the x and y-value of each point by 2.

The picture below shows a dilation with a scale factor of 2. This means that the image, A', is twice as large as the pre-image A. Like other transformations, prime notation is used to distinguish the image fromthe pre-image.
