In this triangle it is clear that the unknown side x is the hypotenuse of both the triangles that are being formed . So , let us take any one of the triangles and with it's length let us find the length of their hypotenuse which is side x .
= 5² + 5² = x² ( according to the pythagorean theorem the square on the hypotenuse will be equal to the sum of the squares on the other two legs )
= 25 + 25 = x²
= 50 = x²
= 7.0710678119 = x
But they have given that we have to round it off to the nearest tenths , so ;
= 7.0710678119 will be equal to = 7.10
= 7.1 = x
Therefore , the length of the unknown side x = 7.1 .
You have the formula already, just plug in 30 for s (speed) and solve for d (distance).

Answer:
50 mph = 50 miles per 60 minutes = 50*105/60 miles in 105 minutes = 87.5 miles.
Step-by-step explanation:
At a constant speed of 60 mph, you are traveling 1 mile per minute. It will take you 50 minutes to travel 50 miles.
hope this helps
Answer:
B. 152 square inches
Step-by-step explanation:
The surface area equation is:
SA=2LH+2LW+2WH
In this problem, length is 6, width is 1 and height is 10. If we plug those numbers into the equation we have:
SA=2(6)(10)+2(6)(1)+ 2(1)(10)
(simplify)
SA=120+12+20
(simplify)
SA=152
