Answer 1

Step-by-step explanation:

According to Pythagoras ,

h² = p² + b²

h = √ p2 + b2

= √ 12

so,

Answer 2

From image we can see That :-

→ DE = Length of Perpendicular = 9m .

→ EF = Length of Base = 3m.

→ Angle EDF = @ = ?

Solution :-

we know That, Tan@ = Perpendicular/Base .

So,

→ Tan@° = EF/DE

→ Tan@° = 3/9

→ Tan@ = (1/3)

→ @ = Tan^(-1) (1/3)

→ @ = 18.43°. ≈ 18.4° .

Hence, Angle D is 18.4°..

Important :-

→ sin theta = Perpendicular/Hypotenuse

→ cos theta = Base/Hypotenuse

→ tan theta = Perpendicular/Base

→ cosec theta = Hypotenuse/Perpendicular

→ sec theta = Hypotenuse/Base

→ cot theta = Base/Perpendicular...
