Answer:
-2 8/9
Step-by-step explanation:
-4 + 2 = -2
1/3 = 3/9
3/9 + 5/9 = 8/9
Hope this helped :)
Answer:
sin A = 3/5
cos A = 4/5
tan A = 3/4
Step-by-step explanation:
Using the trigonometric ratios;
SOH CAH TOA
Sin A = opposite/hypotenuse
cos A = adjacent/hypotenuse
tan A = opposite / adjacent
From the diagram given;
opposite = 3 adjacent =4
We can find the value of the hypotenuse by using the Pythagoras theorem
opposite² + adjacent² = hypotenuse²
3² + 4² =hypotenuse²
9 + 16 =hypotenuse²
25 = hypotenuse²
take the square root of both-side
√25 = √hypotenuse²
5 = hypotenuse
hypotenuse = 5
sin A = opposite / hypotenuse
sin A = 3/5
cos A = adjacent/hypotenuse
cos A = 4/5
Tan A = opposite /adjacent
tan A = 3/4
