In my class, everyone studies French or German, but not both languages. One third of the girls and the same number of boys study German.

Twice as many boys as girls study French.

Which of these could be the total number of boys and girls in my class?

do you mean add both of the equations together

because if you do the answer is 10x-5

step-by-step explanation:

no idea

step-by-step explanation:

answer: the answer is d

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°.
