Question

in the following figure find the value of x and y​

Answer 1

Answer:

The answer of B is x -60°, y -120°

The answer of C is x -90°

Answer 2

Answer:

b.) x=60°

y=60°

Step-by-step explanation:

b.) In ΔAOB,

Sum of measures of all angles of a Δ is 180°.

Therefore,

OAB+AOB+OBA=180°

Therefore,

60°+x°+60°=180°

120°+x°=180°

x°=180°-120°

x°=60°

Vertically opposite angles are always congruent.

Therefore,

In ΔOBC,

OAB=OBC

x=y

60°=y

Therefore,

y=60°

c.) Measure of adjacent angles are always supplementary.

Therefore,

130°+x=180°

x=180°-130°

x=50°

(This measure i. e x=50° is the solution for A)
