T = varsta tatalui
f = varsta fiului
anul acesta: t = 4 x f
peste 20 de ani: t+20 = 2 x (f+20)
=> 4 x f +20 = 2 x f + 2 x 20
4 x f - 2 x f = 2 x 20 - 20
2 x f = 20
f = 10
anul acesta fiul are 10 ani
peste 5 ani fiul va avea...
Answer:
sin S = is the ratio found.
Step-by-step explanation:
It is given that m∠U = 90°
TS is the hypotenuse = 73 units
UT is the adjacent side of the right angle = 48 units
SU is the base of the triangle = 55 units
Now we have to find the ratio as,
sin S =
sin S =
Plugin the values, we will get,
sin S =
So the ratio was found.

Answer:

Step-by-step explanation:

y intercept is when x = 0
So, Putting x = 0 in the above function
=> f(0) = 
=> f(0) = 2*1
=> f(0) = 2
So, y-intercept is (0,2)
