Answer:

Step-by-step explanation:
Given the legs of right angled triangle 4 and 5 units. we have to find the length of hypotenuse.
By Pythagoras theorem,
In right angled triangle the square of the length of the hypotenuse is equal to sum of squares of the lengths of other two sides

Hence, 
<h3>
Answer: C) 70 degrees</h3>
=========================================================
Explanation:
We have n = 6 sides, so the interior angles must add to 180(n-2) = 180(6-2) = 720 degrees
Lets add up the angles, set the sum equal to 720 and solve for x
x+2x+115+2x+115+2x = 720
7x+230 = 720
7x = 720-230
7x = 490
x = 490/7
x = 70
This makes angle 2x = 2*70 = 140 degrees
We see that x = 70 is the smallest angle, so that's why C is the answer.
