Math ? *i think it's b but i just want to make sure*

what is the unit vector of: v: < -6, -8> ?

a. < ⅗, ⅘ >
b. < -⅗, -⅘ >
c. < ⅘, ⅗ >
d. < -⅘, -⅗ >

false

step-by-step explanation:

false : it can not go to 9 the highest that part can go is 7

here is your proof

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°.
