P and Q form a linear pair. If mP = (7x – 4)º and mQ = (2x - 5), find the measure of each angle.
Equation
x=
mP =
mQ =

m∠P=143° and m∠Q=37°

Step-by-step explanation:

(2x-5)+(7x-4)=180°

9x-9=180

9x=189

x=21

2(21)-5=37

7(21)-4=143

step-by-step explanation:

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
