Raul is performing an experiment. He pours water into a glass and measures the temperature of the water at 72.3" Then he adds a few Ice tubes to the glass of water. He measures the temperature of the water again and finds that it has changed by -39.15
Complete the steps below to learn more about the temperature change of the water

Part C rearrange the expression 72.3 + (-39.1) using the commutative property so the terms with the same place value are next to each other

answer: f = 32.2m

step-by-step explanation: that is the answer

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°.
