Answer 1

hello my friend

I am deeply sorry you could not get the answer you wanted

so I am willing to do a deal eh?

give me brainliest and I will give you brainliest how does that sound?

basically what I'm saying is scratch my back and I will scratch yours...

in regards Adonijah

Answer 2

Answer:

EXPLANATION.

cot∅ = 7/8.

As we know that,

cot∅ = 7/8 = Base/perpendicular.

\sf \implies \dfrac{(1 + sin \theta)(1 - sin \theta)}{(1 + cos \theta)(1 - cos \theta)}⟹

(1+cosθ)(1−cosθ)

(1+sinθ)(1−sinθ)

As we know that,

Formula of :

⇒ x² - y² = (x + y)(x - y).

Using this formula in equation, we get.

\sf \implies \dfrac{(1 - sin^{2} \theta)}{(1 - cos^{2} \theta)} = \dfrac{cos^{2} \theta}{sin^{2} \theta}⟹

(1−cos

(1−sin

⇒ cot²∅.

Put the value of cot∅ = 7/8 in equation, we get.

⇒ cot²∅ = (7/8)².

⇒ cot²∅ = 49/64.

MORE INFORMATION.

Fundamental trigonometric identities.

(1) = sin²∅ + cos²∅ = 1.

(2) = 1 + tan²∅ = sec²∅.

(3) = 1 + cot²∅ = cosec²∅.
