Hello from MrBillDoesMath!
Answer:
96 degrees
Discussion:
The base angles of an isosceles triangle are equal and a triangle has 180 degrees. In our case this means that
42 + 42 + (measure of vertex angle) = 180
84 + (measure of vertex angle) = 180 => (subtract 84 from both sides)
84 - 84 + (measure of vertex angle) = 180- 84 =>
(measure of vertex angle) = 180- 84 = 96
Thank you,

It would be 32 1/4 - 30 5/6
129/4 - 185/6
387-370 / 12 = 17/12 = 1 5/12
So, he dived for 1 5/12 inches
The 8 ounce can of tomatoes that costs $1.14 has the better unit price.
Explanation: It’s $0.14 per oz and the 10-ounce can has the unit price of $0.19. The cheaper unit price is the “better” unit price.
13. Collinear means the three points lie on a line. For instance, A, C, and E are collinear.
14. A, C, and D do not lie on the same line, so they are not collinear.
15. Coplanar means the four points are in the same plane. For example, B, C, D, and F lie in the same plane and are coplanar.
16. Yes, the hash marks indicate the lengths are equal.
17. No, there is no evidence the lines are equal in length.
