Question

Sin Cos Tan
Geometry

Answer 1

Sin= opp/hyp
Cos= adjacent/hyp
Tan= opp/adj
1•Sin= 30/50= 0.6
1•cos= 40/50= 0.8
1•tan= 30/40= 0.75
For question 2 goes the same:
2. Sin= 36/27= 1.33
2.cos= 45/27= 1.66
2.tan= 36/45= 0.8
For question 3:
3. Sin= 8/15= 0.533
3. Cos= 17/15= 1.1333
3.tan = 8/17= 0.47

Answer 2

`\sf Sin \ A = (30)/(50)\\\\\\Cos \ A = (40)/(50)\\\\\\Tan \ A = (30)/(40)`

Explanation:

Trigonometric ratios:

1)

`\sf Sin \ A = (opposite \ side \ of \ \angle \ A)/(hypotenuse)`

`\sf =(BC)/(AC)\\\\=(30)/(50)`

`\sf \sf Cos \ A = (adjacent \ side \ of \ \angle \ A)/(hypotenuse)`

`\sf = (AB)/(AC)\\\\= (40)/(50)`

`\sf \sf Tan \ A = (opposite \ side \ of \ \angle \ A)/(adjacent \ side \ of \ \angle \ A )`

`\sf = (BC)/(AB)\\\\= (30)/(40)`
