Question

Find cos(α) in the triangle.

Answer 1

Ⲁⲛ⳽ⲱⲉⲅ:

`\quad\hookrightarrow\quad \sf { (35)/(37) }`

Ⲋⲟⳑⳙⲧⳕⲟⲛ :

In the given triangle , for angle α , we have :

• Base = 35
• Hypotenuse = 37
• Perpendicular = 12

And, cos α for a right angled triangle is the ratio of the adjacent side to the hypotenuse, where α is the acute angle ,i.e:

`\quad\longrightarrow\quad {\pmb{\sf {cos\:\alpha = (Base)/(Hypotenuse) }}}`

Therefore:

`\implies\quad \tt { cos\:\alpha = (B)/(H) }`

`\implies\quad \tt\underline{ \underline{\pmb{{cos\:\alpha =(35)/(37)} }}}`
