si dos autos salen de 2 ciudades distintas entre si 720 kilometros uno hacia el otro el primero lleva una velocidad constante de 40 kilometros por hora y el segundo de 30 kilometros por hora si salen ambos a las 8 a. m. ¿a que distancia se encontraran a las 11 a. m.?

answer: idk

step-by-step explanation:

step-by-step explanation:

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°.
