Answer:
2.) 7.8
Step-by-step explanation:
We can use Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
5^2 + 6^2 = c^2
25+36 = c^2
61 = c^2
Take the square root of each side
sqrt(61) = sqrt(c^2)
7.810249676 = c
Answer:
36
Step-by-step explanation:
X/100% x 140 = 50.4
X x 140 = 50.4 x 100
X x 140 = 5040
X = 5040/140
X = 36
Answer: 3. 4
4.
Step-by-step explanation:
8^2 + 12^3 = c^2
64 + 144 = c^2
208 = c^2
√208

The final answer is the square root of 208
8^2 + b^2 = 17^2
64 + b^2 = 289
-64 64
b^2 = 225
