Answer:

A≈22 | B≈4.4 | C≈13.2

Step-by-step explanation:

5 + 1 + 3= 9

40/9≈ 4.444…

(4.4x5=22)+(1x4.4=4.4)+(3x4=13.2)= 39.6≈40

Idrk if I did this right, but I hope it’s kinda useful (I have a feeling I misunderstood the question lmdao)

$\bold{\huge{\green{\underline{ Solution}}}}$

$\bold{\underline{ Given :- }}$

We have given a right angled triangle whose values are m, n and 2

$\bold{\underline{ To \: Find :- }}$

We have to find the value of m and n

$\bold{\underline{ Let's \: Begin :- }}$

In the given right angled triangle, we have

Perpendicular height = n units
Base = 2 units
Hypotenuse = m units

Now, By using trigonometric ratios 

$\bold{\pink{ Sin Φ = }}{\bold{\pink{\frac{Perpendicular }{Hypotenuse}}}}$

$\bold{\red{ Cos Φ = }}{\bold{\red{\frac{Base}{Hypotenuse }}}}$

$\bold{\blue { tan Φ = }}{\bold{\blue{\frac{Perpendicular }{Base }}}}$

According to the question :-

$\bold{ Cos \: 45° = }{\bold{\frac{2}{m}}}$

$\bold{ 1/√2= }{\bold{\frac{2}{m}}}$

$\bold{\red{ m = 2√2 \: units }}$

We know that , Sum of Angles of triangle is 180° .

Therefore, 

Let the unknown angle be x

$\sf{ 45° + x + 90° = 180° }$

$\sf{ x = 180° - 135 ° }$

$\sf{ x = 45° }$

Now, 

$\bold{ Cos \: x° = }{\bold{\frac{n}{2√2}}}$

$\bold{ Cos \: 45° = }{\bold{\frac{n}{2√2}}}$

$\bold{ 1/√2= }{\bold{\frac{n}{2√2}}}$

$\bold { n = 2√2/√2 }$

$\bold{\red{ n = 2\: units }}$

Thus, The value of m = 2√2 and n = 2

$\sf{\blue{ Hence, \: option \: D \: is \: Correct }}$

Two cars, A and B, are travelling along a straight road and in the same direction. Car B is 20 km

pishuonlain [190]

Answer:

2 o'clock

Step-by-step explanation:

Their 'closing speed' is 60 - 50 = 10 km/hr

they have 20 km between them

at closing speed this will take 20 km / 10 km/hr = 2 hours for the cars to meet....this would be at 14:00 or 2 oclock

The volume of a sphere is 5000 pi meters cubed. What is the surface area

faltersainse [42]

I hope this helps you

5000.pi=4/3.pi.r^3

r^3=3750

r=15,53

Surface Area=4pir^2

Surface Area =4.pi. (15,53)^2

Surface Area =964,72.pi
