Answer:
x = 135
Step-by-step explanation:
The three triangles are similar.
144/y = y/81
y^2 = 144 * 81
y = 12 * 9
y = 108
81^ + 108^2 = x^2
x^2 = 18225
x = 135

Answer:
Add the exponents and keep the bases the same. Then find the reciprocal and change the sign of the exponent
Step-by-step explanation:
When multiplying exponents with the same base number, you can add the powers. (If it was dividing, you would subtract the powers). You would then get
.
- 2³ = 8,
- 2² = 4,
- 2^1 = 2,
- 2^0 = 1
The pattern is to divide by 2. This means that
would be 1 ÷ 2 which is 1/2.
Tip: Any number to the power of -1 means to give its reciprocal.
Hope this helps!
