Answer:
The answer is 
Step-by-step explanation:
The triangle isosceles has two equal angles and two equal sides
The triangle ABC is an isosceles triangle -----> see the attached figure
-----> radius of the circle
------> angles of the base of the isosceles triangle ABC
------> by central angle ( vertex angle of the isosceles triangle ABC)
Remember that
the sum of the internal angles of a triangle is equal to 
so
1/16 of a pint because really there are 16 ounces in a one pint
Answer:
x = π/6, π/2, 5π/6, 3π/2
Step-by-step explanation:
cos x = sin(2x)
Use double angle formula.
cos x = 2 sin x cos x
Move everything to one side and factor.
cos x − 2 sin x cos x = 0
cos x (1 − 2 sin x) = 0
Set each factor to 0 and solve.
cos x = 0
x = π/2, 3π/2
1 − 2 sin x = 0
sin x = 1/2
x = π/6, 5π/6
The total solution is:
x = π/6, π/2, 5π/6, 3π/2
55*2=110, 360-110=250, 250/2=125. The answer is 125°.
