Question

Round your answer to the nearest hundredth.

Answer 1

Answer:

4.28

Step-by-step explanation:

basically using the sine ratios :

a/sinA = b/sinB = c/sinC

so, let's call the known side a (3) and its opposing angle A (35 degrees).

and we know C is 90 degrees.

sin(90) = 1

b = the missing side AC.

and because the sum of all angles in a triangle is always 180 degrees, the missing angle B is

B = 180 - 90 - 35 = 55

AC/sin(55) = 3/sin(35)

AC = b = sin(55) × 3/sin(35) = 4.28

a little more practice and calculate also c that way :

3/sin(35) = c/1

c = 3/sin(35) = 5.23

Answer 2

Answer:

Hello there, lol.

Adjacent = Opposite/ Tan(35)

Adjacent = 4.3
