The acute angles of a ________ triangle are complementary

1 answer:

4 0

Answer:

Complementary angles are two angles that add up to 90 degrees. If angle C is a right angle, then it has a measure of 90 degrees. The angles in a triangle must sum to 180 degrees. If one angle is already 90 degrees, then the other two angles must sum to 90 degrees since 180- 90 = 90.

a tourist drove his car for the total of 17.5 hours while on a 3-day vacation on the first day he drove 4.5 hours in the second

AleksAgata [21]

Answer:

1.75 hours

Step-by-step explanation:

Time for day 1 : 4.5 hrs

Time for day 2: (4.5 ×2.5)

Time for day 3: let it be denoted by a variable ,say T.

Total Time= 17.5

(Time for day 1 ) + (Time for day 2) +(Time for day 3) =17.5

4.5 + (4.5×2.5) + T = 17.5

4.5+11.25+T =17.5

15.75+T=17.5

T=17.5-15.75

T= 1.75
