Question

tan A =10÷26 find sin A​

Answer 1

Answer:

Sine, Cosine and Tangent are the main functions used in Trigonometry and are based on a Right-Angled Triangle. Before getting stuck into the functions, it helps to give a name to each side of a right triangle:

Step-by-step explanation:

Answer 2

Answer:

Sin A = 10/ 2√194

Step-by-step explanation:

Tan A = Perpendicular/ Base = 10/26

In ∠ABC,

Right angle at B

Perpendicular = CB = 10

Base = AB = 26

Hypotenuse = AB = ?

By Pythagoras Theorem

AC² = AB² + CB²

=> AB² = 26² + 10²

=> AB² = 676 + 100

=> AB² = 776

=> AB = √776

AB = 2√194

Hypotenuse = 2√194

Sin A = Perpendicular/ Hypotenuse = 10/ 2√194
