Answer:
Step-by-step explanation:
you might be getting a bit confused here, that formula is the pyhthagorus theorem, which you use to solve the sides of a right angled triangle. if two of the sides of a right angled triangle are, lets say 3cm and 4cm, and you are trying to get the answer for the hypotenuse(the longest side, also the side opposite the right angle) then you do
3²+4²=c²
9+16=c²
25=c²
c=5
(that was just an example btw)
edit: im just going to keep that up there because it may be helpful, but i just realised you question.
to find b in
a²+b²=c²
it would be easier if you knew the other two, like wayyyy easier.
but what you would do is , lets say a was 3 and c was 5, then
3²+b²=5²
9+b²=25
b²=25-9
b² =16
b=√16
b=4
Hopefully this helps!!
Answer:
Original number = 54
Reversed number = 45
Step-by-step explanation:
Let the tens place digit be x and unit's place digit be y.
Therefore, required no. = 10x + y
Number obtained after interchanging the digits = 10y + x
According to the given condition:
Answer: x= 7
Step-by-step explanation:
-2x= -14 Divide both sides by -2
x= 7
check
-2(7) = -14
-14 = -14
Answer: A) 6/8
==================================================
Explanation:
The tangent of angle A is the ratio of the opposite and adjacent sides. So you just form a fraction of the opposite side (6) and the adjacent side (8)
The opposite side is the leg furthest from the reference angle A. The adjacent side is the leg closest to the angle A. Normally you would reduce the fraction as much as possible, but your teacher has chosen not to do so in this case.
The underlined digit equals 20.
