lapo4ka [179]

Answer:

73.68%

Step-by-step explanation:

To find the amount of increase subtract 33-19 to get 14.

The percent increase is the amount of increase/initial length * 100

So 14/19*100 = 73.684...

Rounding to the nearest hundredth = 73.68%

Please help answer these questions. My teacher said they were really easy but I just don't understand. Will mark brainliest !!!

Answer:

1.  A = 59

2.  A = 43

Step-by-step explanation:

If we have a right triangle  we can use sin, cos and tan.

sin = opp/ hypotenuse

cos= adjacent/ hypotenuse

tan = opposite/ adjacent


For the first problem, we know the opposite and adjacent sides to angle A

tan A = opposite/ adjacent

tan A = 8.8 / 5.2

Take the inverse of each side

tan ^-1 tan A = tan ^-1 (8.8/5.2)

A = 59.42077313

To the nearest degree

A = 59 degrees


For the second problem, we know the  adjacent side and the hypotenuse to angle A

cos A = adjacent/hypotenuse

cos A = 15.3/21

Take the inverse of each side

cos ^-1 cos A = cos ^-1 (15.3/21)

A = 43.23323481

To the nearest degree

A = 43 degrees
