(1 po Find the values of angles h, f, and g.
h 60°
20°
130°
g
Oh=40°; f= 20°; g = 50°
Oh=30°; f= 60°; g = 50°
Oh=30°; f= 70°; g = 50°
Oh=60°; f= 20°: g = 50°

The measure of ∠JHG is 70 degrees

Step-by-step explanation:

If you have one of angle's sides by 0° at protractor then the other side crosses the measure of angle.

2, 2, 2 or -4, 20, 29

step-by-step explanation:

there is two ways you can do it.

1. 180°. the sum of the interior angles of a triangle is 180°, for the equilateral triangle that it has three equals side is 60°+60°+60°=180°.

2. 60°. each interior angle of a equilateral triangle is 60°

3. 120°. the measure of ∠m is 120°, the sum of the angles ∠m and ∠n is equal to 180°. so, in order to find the measure of ∠m, we have ∠m+∠n=180° > ∠m=180°-∠n > ∠m=180°-60°=120°.

4. 360°. the sum of the exterior angles of an equilateral triangle is ∠m+∠r+∠x=120°+120°+120°=360°. the exterior angles of any triangle always add 360°.
