It would be: (x,y) = (-1,-1)
-x-2 = 3x+2
3x+x = -2-2
x = -4/4
x = -1
Put that value in 1st equation, y = -(-1)-2 = 1-2 = -1 SOLVED
The answer would be 2√5/5
As a rule, you cannot have any radical as a denominator. That's why you gotta multiply √5 with √5 which would be √25. The square root of this is 5, and now you have disposed of the radical! Hurray. However, keep in mind, that when you multiply √5, you also multiply it to the numerator. So, yeah, after this, you get the answer.
Hopefully, my explanation makes sense. :)
Answer:
I am almost 100% sure it is A
Step-by-step explanation:
Answer:
46.63 ft
Step-by-step explanation:
I've drawn and attached a triangle diagram to represent this elevation and distance of balloons.
Now, from the diagram attached, we can see the angle at which June must look up to see Armando is 25°.
Also, the height of Armando above June is represented by "x".
Thus, using pythagoras theorem, we can find x.
Thus;
x/100 = tan 25
x = 100 × tan 25
x = 100 × 0.4663
x = 46.63 ft
