Not sure if my picture answer make sense so, when you have a^2 and b^2 to find c^2 u add then and then square root it to get c. e.g 81^2 + 108^2 = 18225 then u square root it and get 135. when u are given the hypotenuse (which is always c^2) u take that away from the a^2/b^2 and square root. e.g 8^2-4^2 which is 48 which can’t be square rooted so just leave as root48
Answer:
a=k1
B=125
Step-by-step explanation:
Given :
a=3
B=64
According to question
a ∝
therefore
a=k1 ........Eq(1)
K1=......Eq(2)
Putting the value of a and B we get in Eq(2) we get
Putting the value of k1 in Eq(1)
.......................Eq(3)
putting the value of a=15/4 IN Eq(3) we get
