The vertex angle bisector divides the triangle into two congruent right triangles. The sine of half of the vertex angle will be half of the base divided by the side (from the definition of the sine of an angle). Then the total vertex angle is ...
α = 2×arcsin(3.5/5) ≈ 88.9°
_____
Using the Law of Cosines, the vertex angle can be found as
arccos((7^2 -5^2 -5^2)/(-2*5*5)) = arccos(1/50) ≈ 88.9°
Answer:
its correct
Step-by-step explanation:

Answer: 12 refills
Step-by-step explanation:
y = 8.95 + 1.50x
26.95= 8.95 + 1.50x
26.95 - 8.95 = 1.50x
18 = 1.50X
18 / 1.50 = x
X = 12
Answer:
A

I believe that angle 6 is 108 because I drew to the best of my ability and I see that 3 and 6 are alternate interior angles.
