Round 55 to the nearest tenth and then divide the number by 2

30

Step-by-step explanation:

55 rounded to the nearest ten is 60

60/2=30

30

Step-by-step explanation:

55 is closer to 60 than 40. And you divide 60 by 2 you get  30.

150.6

all i did was i multiplied 5.02 by 30

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°.
