(9x+1/2)+(7x-9 1/12)
miv72 [106K]

Step-by-step explanation:

Input Equation can be rewritten:

= (9*1/2)+(7*-91/12)

= (9/2)+(7*-91/12)

= (4.5)+(7*-91/12)

= 4.5+(7*-91/12)

= 4.5+(-637/12)

= 4.5+(-53.083333333333)

= 4.5+-53.083333333333

= 4.5-53.083333333333

= -48.583333333333

hope this helps!

Inscribed circles on the arc; improvement answer is required in full.
e-lub [12.9K]

Answer:

The measure of an inscribed angle is half the measure of the intercepted arc

∠EFG creates Arc EDG

if ∠EFG is 1/2 arc EDG then 115° x 2 = 230°

A circle is 360°.

The remaining arc EFG is 360° - 230° = 130°

∠EDG is 1/2 of arc EFG so, 130° ÷ 2 = 65°

∠EDG = 65°
