In a right triangle abc, angle c is a right angle and cos b =255/257.

what is the measure or angle a?

a)7.2 degrees

b)83.2 degrees

c)82.8 degrees

d)90.0 degrees

C

Step-by-step explanation:

Given

cosB = = =

Then the hypotenuse AB = 257 and BC = 255

sinA = = =

A = () = 82.8° → C

answer: 1,380

step-by-step explanation:

1: you turn %15 into a decimal by moving the decimal point two places to the left.

2: and then you multiply .15 by 1,200 , which will get you 180.00

3: from there you will add 180 to 1,200

4: which will get you 1,380

hope it *im kind of slow so idk if my answer is right*
