Determine the domain and range of the given function. the domain is
A. all real numbers
B. all real numbers greater than or equal to -2
C. { x:x =-2,-1,0,1,2}
D. {y;y=-2,-1,0,1,2}

the range is
A. all real numbers
B. all real numbers greater than or equal to -2
C . and D. same as last one

the answer is -1 for this question

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°.
