Hi! Does anyone know the slope of these tables, i don’t really understand too well so explanations would be appreciated giving out 20 points to someone who knows all! ty!

answer: 1 and 3

step-by-step explanation:

236 cm 16 time 12 = 192

6 times 7 = 42

192+42

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°.

the answer is  

d.

i did this one. so you should get it right.
