Answer:
sqrt(50)
Step-by-step explanation:
Since it is a right triangle, we can apply the Pythagorem Theorem.
a^2 + b^2 = c^2
25 + 25 = c^2
50 = c^2
c = sqrt(50)
Answer:
9.2 (1DP)
Step-by-step explanation:
- First you do 10^2 which is 10 X 10 = 100
- Then you do 4^2 which is 4 X 4 = 16
- Then you do 100 - 16. The way Ive learnt it is that if the hypotenuse isn't the one you have to find then minus of it it is then plus. So 100 - 16 = 84
- A^2 + B^2 = C^2 84 is C^2 meaning now you have to square root it
- Square root of 84 is 9.2 to 1 DP
