Mathematics

Yakvenalex [24]2 years ago
3 0
We have an equation: 250/?= 50/100

Cross multiply:
50*?= 250*100
⇒ ?= 250*100/50= 500

The number is 500~

We have another equation: ?/500= 80/100

Cross multiply:
100*?= 80*500
⇒?= 80*500/100= 400

80% of 500 is 400~

Find csc x if sin x + cot x cos x =√3.
Oksi-84 [34.3K]

Answer:

The answer is (d) ⇒ cscx = √3

Step-by-step explanation:

∵ sinx + (cotx)(cosx) = √3

∵ sinx + (cosx/sinx)(cosx) = √3

∴ sinx + cos²x/sinx = √3

∵ cos²x = 1 - sin²x

∴ sinx + (1 - sin²x)/sinx = √3 ⇒ make L.C.M

∴ (sin²x + 1 - sin²x)/sinx = √3

∴ 1/sinx = √3

∵ 1/sinx = cscx

∴ cscx = √3
