Tan 45°. tan² 30° tan 60° slove it

makvit [3.9K]

Answer:

$\frac{\sqrt{3} }{3} or \frac{1}{\sqrt{3} }$

Step-by-step explanation:

We can break the problem into three parts,

tan45 = sin(45)/cos(45)= $\frac{\frac{\sqrt{2}}{2} }{\frac{\sqrt{2}}{2} } =1$

$tan^{2}30 =(tan30))^{2}=(sin30/cos30)^2=((1/2)/(\sqrt{3}/2))^2 =(1/\sqrt{3})^2$

$tan60=sin60/cos60=\frac{\sqrt{3}/2 }{1/2} =\sqrt{3}$

Then, $tan45*tan^230*tan60=1*(1/sqrt(3))^2*sqrt(3)=1/sqrt(3)=sqrt(3)/3$

Therefore, the solution is sqrt(3)/3

Solve and show your work for each question.

Harlamova29_29 [7]

Answer:

9/20

Step-by-step explanation:

You set the fraction up at first as 45/100. Then you know that 5 goes into each so you divide by 5 $\frac{45}{100} /5$

45/5=9

100/5=20

You get 9/20, and this is in simplest form.

The 90km/h bus runs between the two stations in 2 hours and 20 minutes.

AnnZ [28]

Answer:

1. distance is 210km

2. distance is 163•3km

Step-by-step explanation:

SPEED=DISTANCE÷TIME

90km/h= X ÷ 2 hrs and 20mins

CHANGE 20 MINS INTO HRS

1 hr = 60mins

? = 20mins

20mins * 1hr= 1/3hr

60mins

Speed=distance÷time

90km/h= X ÷ 21/3

Distance= speed * time

X = 90km/h * 21/3hrs

distance is 210km

Speed=distance ÷

70km/h= X ÷ 21/3hrs

Distance=speed * time

X = 70km/h * 21/3hrs
