Answer:
Step-by-step explanation:
∠ABC = 1/2 ∠AOC
since we know ABC = 30° we can solve for AOC with a bit of Algebra
30 = 1/2 AOC
60 ° = AOC
:) does it make sense?
the formula about is for inscribed angles , that is an angle that touches the outside of the circle and then goes through the other side. :) Like ∠ABC
Answer:
Option (A)
Step-by-step explanation:
By applying the theorem angle theorem in the given triangle,
Sum of exterior angle of a triangle is equal to the sum of opposite interior angles of the triangle.
Therefore, 130° = y° + y°
130° = 2y°
y = 
y = 65°
Therefore, measure of interior angles 'y' of the given triangle will be 65°.
Option (A) will be the answer.
Answer:
9 + 4x = 101
Step-by-step explanation:
9 + 4x = 101 Equation
( +9 - 9 ) + 4x = ( 101 - 9 ) Subract 9 on both sides
4x = 92 Simplify
x = 23 Divide 4 on both sides
