Leanna opens a saving account with an initial balance of $100. She then deposits $50 each month. Use an equation to explain the relationship between the amount of money in the account, a, and the number of months since Leanna opened the account, m.

1. 34

2. 268

3. x=14.4

step-by-step explanation:

yard and mile are too big.

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°.
