<u>Answer:</u>
5x = 100°
4x = 80°
<u>Step-by-step explanation:</u>
We are given a diagram with a straight line AC being intersected by another line BD and we are to find the two mentioned angles.
We know that the two angles (5x° and 4x°) are supplementary so their sum would be equal to 180°.
So we can write it as:
Finding the measure of both the angles:
100°
80°
Answer:
k=45
Step-by-step explanation:
Since the sum of the measures are 180 and the measures are 45 degrees, k degrees, and 2k degrees, we can conclude that . 2k and k are like terms, so you can add 2k and k to get 3k.Then, you would have
. Since you are finding k, you want to isolate k as best you can. To do this, you subtract 45 on both sides
as shown by the equation, 180-45 is 135. Then, you divide 3 on both sides to get k=45.
Answer:
1.25
Step-by-step explanation:
Calculate the scale factor as the ratio of the corresponding sides of the image to the original.
here the image is 6.25 and the original is 5
scale factor = = 1.25
This represents an enlargement
