Answer:
15.6
Step-by-step explanation:
the traingle is right so u have to apply the pythagorean theorem to find x so x^2=10^2+12^2=244
so x=15.6
So you have a right angle triangle. You need to use trig for this, as you have two values you can figure out a third.
You know that you have
90 deg. angle
19 deg. angle
Therefor you have 71 deg. angle
sin19 = x/15
15sin19 = x
x = 2.2
Now do Pythagoras c^2-b^2=a^2
a = 14.8
So the sides are 2.2 and 14.8 units long. (If these numbers are wrong tell me and I'll edit answer)
Step-by-step explanation:
3 - 11x
x is "a number".
so, the request is to multiply it by 11 and subtract the result from 3.
When two variables varies inversely with each other, their product is always constant.
Since y = 4 when x = 4, their constant product is 16.
So when x = 2, y = 8.
