How do i solve 15 x 18 + 12 ÷ 3 + 9

Solution answer is 283

Step-by-step explanation:

15 x 18 + 12 ÷ 3 + 9

Using D M A S rule,first divide

=15 x 18 + 4 +9

=270 +4 +9

=283

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
