√8
for the equations of circles: x²+y²= (radius)²
Maybe 430 or 400 could be the answer to that problem
Answer:
Step-by-step explanation:
Pythagorean theorem,
hypotenuse² = Base² + altitude²
= 8² + 10²
= 64 + 100
= 164
hypotenuse = √164 = 12.8 cm
Remember them is the best way to go.
draw the exact value triangles if you're unsure, but importantly, you just need to memorise these exact values.
Answer:
n = 143
Step-by-step explanation:
To find the value of n, you multiply 13 by 10 because that is the inverse of dividing, and you get 130. Since there is a greater than sign, the answer is 143 because the value of n has to be greater than 130.
