The measure of the angles of a triangle are in the ratio 5: 6: 7. find the measure of the largest angle

70°

add the parts of the ratio 5 + 6 + 7 = 18

the sum of the 3 angles in a triangle = 180°

divide 180 by 18 to find 1 part of the ratio

= 10° ← 1 part of ratio

5 parts = 5 × 10 = 50°

6 parts = 6 × 10 = 60°

7 parts = 7 × 10 = 70° ← largest angle

note that 50° + 60° + 70° = 180° ← check

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

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
