Angles abc, bcd, cda and dab are inscribed angles and form intercepted arcs. (a) find the value of x (b) find the value of y (c) find the value of z

Step-by-step explanation:

The rule required here is that the measure of an inscribed angle is half the measure of the arc it intercepts.

(a) ∠BCD = 90°, so arc BAD is ...

... x + 60° = 2×90°

... x = 180° -60° = 120°

(b) ∠ABC = 100°, so arc ADC is ...

... x + y = 2×100°

... y = 200° -120° = 80°

(c) From part A, we know that arc BAD = 180°, so arc BCD = 180° (since they add to make 360°). Arc BCD is ...

... y + z = 180°

... z = 180° -80° = 100°

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
