Tricia has the same number of nickels and dimes in her pocket. the coins total $3.60. how many of each coin does she have? a) 12 nickels and 12 dimes b) 24 nickels and 24 dimes c) 36 nickels and 36 dimes d) 48 nickels and 48 dimes

B

Step-by-step explanation:

Find out the total value of each option and see which one gives a total of $3.60

For A, 12 nickels + 12 dimes = 12 x $0.05  + 12 x $0.10 = $1.80 ≠ $3.60

For B, 24 nickels + 24 dimes = 24 x $0.05  + 24 x $0.10 = $3.60 (correct)

For C, 36 nickels + 36 dimes = 36 x $0.05  + 36 x $0.10 = $5.40 ≠ $3.60

For D, 48 nickels + 48 dimes = 48 x $0.05  + 48 x $0.10 = $7.20 ≠ $3.60

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°.
