Tan(A) = opposite / adjacent
if we call opposite "a" and adjacent "b"
tan(A) = a/b
then...
tan(B) = b/a
because it's on the other angle so "b" is now opposite angle B and "a" is adjacent.

So really you just need to take the reciprocal of the given values.

6. tan(A) = 1.25
reciprocal is flipping the value and using it to divide by 1.

you can keep as decimal , 1/1.25 = 0.8
or change to fraction
1.25 = 5/4

tan(B) = 4/5 or 0.8

7. tan(B) = 0.5
1/0.5 = 2
tan(A) = 2

8. tan(B) = 1
tan(A) = 1

Alina and Asim share Rs 210 in the ratio 2:5. How much money did each of them get?

slavikrds [6]

Answer:

Step-by-step explanation:

Alina=2x---eq(1)

Asim=5x----eq---(2)

So,we get

2x+5x=210

7x=210

x=30

Now,Putting '30' in eq 1 and eq 2

2*30=60

5*30=150

Therefore Alina got 60 Rs while Asim got 150 Rs

Amiraneli [1.4K]

Answer:

Step-by-step explanation:

Substitute 50 for y in the formula

5x+10y=800

5x+10*50=800

5x+500=800

5x=800-500

5x=300

x=300/5

x=60
