What is 9x5/8?

5.625

Step-by-step explanation:

First you should multiple the 9 and the 5. You should do this first because of the order of operations. Then once you get what 9×5 is, 45 then you will procide to divide your first answer 45 by 8. You may know that 8 can go into 45 evenly 5 times. However 5×8 is 40 so you will have to keep diving out until you no longer have any left over numbers. So eventually you will get 5.625 as your final answer.

5 5/8

Step-by-step explanation:

How you get that is by writing the problem down and putting a 1 under the 9 and then multiply 5/8 which equals 45/8 and then that equals 5 5/8

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°.
