C. 700+140+11. You basically add the hundreds, tens, and ones.

A certain ceiling is made up of tiles. Every square meter of ceiling requires 10.75 tiles. Fill in the table with the missing va

ANEK [815]

Answer:

See Explanation

Step-by-step explanation:

Given:

See Attachment

Required

Complete the table

From the question, we understand that:

$1m^2 = 10.75\ tiles$

So:

When square meters = 1

$X = 10.75 * 1$

$X = 10.75$

When square meters = 10

$X = 10.75 * 10$

$X = 107.5$

Assume any value of square meter for the third row;

Say: square meters = 20

$X = 10.75 * 20$

$X = 215$

When square meters = a

$X = 10.75 * a$

Urgent!! I will give brainiest to right answer

Over [174]

Answer:

1) option c

2) option d

3) option a

4) option a

5) option c

Step-by-step explanation:

1. Given that in ΔRST, ∠R=63°, ∠T=90° and so ∠S=27°

Also, cosec=hyotenuse/opposite side

Given RS=23 and ST=10.4

So, cosec27=RS/RT=23/RT

sec=hypotenuse/adjacent side

sec27=RS/ST=23/10.4

And cot=adjacent/opposite side

So, cot63=RT/ST=RT/10.4

2. formula:- sinθ=opposite side/hypotenuse

cosecθ=hypotenuse/opposite side

∴ sinθ *cosecθ = (opposite side/hypotenuse) * (hypotenuse/opposite side) = 1

3. Formula :- tan(360-θ) = -tanθ

∴ tan(300) = tan(360-60) = -tan30°

tan30° = √3

∴tan300° = -√3

5. sinθ= opposite side/hypotenuse

cosecθ = hypotenuse/opposite side

∴ cosecθ = 1/sinθ

Given sinθ = 0.3090

∴ cosecθ = 1/0.3090 = 3.2362
