PLEASE HELP I NEED TO PASS THIS if u help) what is the length of A? (round to the nearest tenth)

what is the length of c? (round to the nearest tenth)

what is the measure of angle A?

a = 5.3

c = 11.3

m∠A = 28°

Step-by-step explanation:

Note:  You need to memorize the definitions of all the trig functions,  Then this type problem will be easy for you.  OK?

For example, tan of an angle = opposite side/adjacent side.

Tan 62 = 10/a

a tan 62 = 10

a = 10/tan 62 = 5.3

sin 62 = opp side/hypotenuse

          = 10/c

c sin 62 = 10

c = 10/sin 62

  = 11.3

The acute angles of a right triangle are complementary.

m∠A + 62 = 90

m∠A = 28°

Now, you try one on your own.

step-by-step explanation:

because there are always 10 numbers in a phone number.
