Answer:
x = 6.8
Step-by-step explanation:
The angle where the tangent meets the diameter is a right angle. This means the triangle is a right triangle and the Pythagorean theorem applies.
x² = 3.2² +6² . . . . . . . . the radius is 3, so the diameter is 6
x² = 46.24
x = √46.24 = 6.8

This is an 8-15-17 right triangle, scaled by a factor of 0.4.
Answer:
Given the total area of the U.S. = 3.79 million square miles
The area of Alaska = 0.67 million square miles
Step-by-step explanation:
We have given the area of the United States and the area of Alaska. Since Alaska is a part of the United States so the area of Alaska is already included in the given area of the U.S.
Thus to find the probability that the meteor will hit Alaska can be calculated by dividing the area of Alaska from the area of the U.S.
The probability to hit the Alaska = 0.67 / 3.79
The probability to hit the Alaska = 0.1767
If the width is w and the length is l, then l-3=w. In addition, l*w=340. Substituting l-3 for w, we get l*(l-3)=340 and l^2-3l=340, then l^2-3l-340=0. Using the quadratic formula, we get l= (3+-sqrt(9+1360))/2=(3+-37)/2 = 20, -17. Since -17 can't be the length, the length is 20. In addition, since l-3=w, w=17
