What is value of x and y

explain

Step-by-step explanation:

triangle ADB and ADC are congruent.

So ∠B = ∠C

∠B = 47

∠ADC = ∠ADB

∠ADC + ∠ADB = 180   { straight angle}

2∠ADB =180

∠ADB = 180/2

x = 90

In ΔADB,

∠B + x + y = 180    { sum of all angles of triangle}

47 + 90 + y = 180

137 + y = 180

y = 180 - 137

y = 43

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh
