In triangle opq right angled at p op=7cm,oq-pq=1 determine the values of sinq and cosq
soldi70 [24.7K]

Answer:

see explanation

Step-by-step explanation:

let pq = x

given oq - pq = 1 then oq = 1 + x

Using Pythagoras' identity, then

(oq)² = 7² + x²

(1 + x)² = 49 + x² ( expand left side )

1 + 2x + x² = 49 + x² ( subtract 1 from both sides )

2x + x² = 48 + x² ( subtract x² from both sides )

2x = 48 ( divide both sides by 2 )

x = 24 ⇒ pq = 24

and oq = 1 + x = 1 + 24 = 25 ← hypotenuse

sinq = \frac{opposite}{hypotenuse} = \frac{7}{25}

cosq = \frac{adjacent}{hypotenuse} = \frac{24}{25}

Ben has 3 times as many guppies as goldfish if he has a total of 20 fish how many guppies does have?
kondor19780726 [428]
Guppies: u
Goldfish: o

3 times as many guppies as goldfish
3*o = u   (there are more guppies than goldfish)

o + u = 20
o = 20 - u

Substitute in (20 - u)  for o in the first equation and solve:
3* (20 - u) = u
60 - 3u = u
60 = 4u
u  = 15

He has 15 guppies. Then substitute in the number of guppies into either equation to find the number of goldfish:
o + u = 20
o + (15) = 20
o = 5

Hope this helps! :)
