Step-by-step explanation:
Since AD bisects BC,
BD = DC.
Therefore 5x - 10 = 3x + 10 and x = 10.
Answer:
The answer for the first picture is 84
The answer for the second picture is 36
Step-by-step explanation:
The first triangle is a isosceles triangle which means that two angle lengths must be the same. We use the only angle measurement which is 48 and subtract it from 180 twice because there are two angles lengths that are the same, once we subtract from 180 we have 84. The same process is followed for the second triangle.
180-48-48=84
Second Triangle:
180-72-72=36
I think it’s D, hope that helps
Answer:
14 points
Step-by-step explanation:
The second test Lee did was 13 points fewer than the first test, which was 91 points, so the second test's score is 91 - 13 = 78 points.
The third test had the score of 92, so this is the highest score, and the lowest score is the second one: 78 points.
The difference between Lee's highest and lowest scores is:
92 - 78 = 14 points
