Question

what is m∠gfi?

m∠gfi =
submit

Explanation:

Step1: Recall the total degrees in a circle

A full circle has \(360^{\circ}\).

Step2: Subtract the known angles

We know one angle is \(90^{\circ}\) (the right - angle) and another is \(140^{\circ}\). Let \(m\angle GFI=x\). Then \(x + 90^{\circ}+140^{\circ}=360^{\circ}\).

$$x=360^{\circ}-(90^{\circ} + 140^{\circ})$$

$$x=360^{\circ}-230^{\circ}$$

$$x = 130^{\circ}$$

Answer:

\(130\)
