kotykmax [81]3 years ago
7 0

Answer: To solve such problems we need to know about Trigonometry.

Trigonometric functions

where perpendicular is the side of the triangle which is opposite to the angle, and the hypotenuse is the longest side of the triangle which is opposite to the 90° angle.

The value of x is 5√3.

Explanation: Given to us,

the base for the triangle, AB = 5 units,

Hypotenuse for the triangle, BC = 10 units,

∠B = 60°,

Solution

The question can be solved in two ways,

1.   Using the Pythagoras theorem,

According to Pythagoras theorem,

substituting the values,

2. using the trigonometric function for ∠B,

for ∠B in ΔABC,

substituting the values,

we know that value of tan(60°) is √3,

Hence, the value of x is 5√3.

Finish the song Ra Ra Rasputin there was a
Ainat [17]

Answer:

This is the lyrics to Rasputin:

There lived a certain man in Russia long ago

He was big and strong, in his eyes a flaming glow

Most people looked at him with terror and with fear

But to Moscow chicks he was such a lovely dear

He could preach the bible like a preacher

Full of ecstasy and fire

But he also was the kind of teacher

Women would desire

Ra ra Rasputin

Lover of the Russian queen

There was a cat that really was gone

Ra ra Rasputin

Russia's greatest love machine

It was a shame how he carried on

He ruled the Russian land and never mind the czar

But the cassock he danced really wunderbar

In all affairs of state he was the man to please

But he was real great when he had a girl to squeeze

For the queen he was no wheeler dealer

Though she'd heard the things he'd done

She believed he was a holy healer

Who would heal her son

Ra ra Rasputin

Lover of the Russian queen

There was a cat that really was gone

Ra ra Rasputin

Russia's greatest love machine

It was a shame how he carried on

But when his drinking and lusting and his hunger

For power became known to more and more people

The demands to do something about this outrageous

Man became louder and louder

This man's just got to go, declared his enemies

But the ladies begged, don't you try to do it, please

No doubt this Rasputin had lots of hidden charms

Though he was a brute they just fell into his arms

Then one night some men of higher standing

Set a trap, they're not to blame

Come to visit us they kept demanding

And he really came

Ra ra Rasputin

Lover of the Russian queen

They put some poison into his wine

Ra ra Rasputin

Russia's greatest love machine

He drank it all and said, I feel fine

Ra ra Rasputin

Lover of the Russian queen

They didn't quit, they wanted his head

Ra ra Rasputin

Russia's greatest love machine

And so they shot him 'til he was dead

Oh, those Russians

<h3>What is HClO3 known as?</h3>

This HClO3  is known to be popularly called as Chloric acid.

Percentage mass of chlorine is formula:

Percentage mass composition = mass of element * 100%/mass of compound.

Therefore;

HClO3 (gram-formula mass = 84 g/mol)

Percentage mass composition of chlorine = 35 * 100% / 84 = 42%

See full question below.

In which compound is the percent composition by mass of chlorine equal to 42%?

(1) HClO (gram-formula mass = 52 g/mol)

(2) HClO2 (gram-formula mass = 68 g/mol)
