In triangle abc, the measure of angle b is 45 degrees more than three times the measure of angle a. the measure of angle c is 60 degrees more than the measure of angle a. find the measure of each angle.

A = 24, B = 72, C = 84 (All in degrees)

Step-by-step explanation:

Given triangle ABC,

angle B = 3A

angle C = 60 + A

(All in degrees)

Sum of angles in a triangle = 180 degrees, therefore

A +B + C = 180

A + 3A + 60 + A = 180

5A = 180 - 60

5A = 120

A = 120/5

A = 24

B = 3A = 3 × 24

B = 72

C = A + 60

C = 24 + 60

C = 84

Therefore measure of A,B,C are 24, 72 and 84 (all in degrees) respectively.

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
