In a 45-45-90 triangle, what is the length of the hypotenuse when the length of one of the legs is 11 in.?

Answers

Answer 1
Answer:

Answer:

= 15.556 in

Step-by-step explanation:

Since this is a 45-45-90 triangle, we can tell that;

  • This is a right triangle  
  • This is an isosceles triangle

One of the theorems of geometry, the Isosceles Right Triangle Theorem, says that the hypotenuse is √2 times the length of a leg.

Therefore;

hypotenuse = leg × √2

If we take hypotenuse as x

Since the leg is 11;

Then; x = 11√2

x = 11/√2

x = 15.556 in

The average height of three students is 68 inches. If two of the students have heights of 70 inches and 72 inches respectively, then what is the height (in inches) of the third student?

Answers

It's 62 inches

70+72+62= 204/3= 68
Write the following equation:

(70+72+x)/(3)=68\n \n 142+x=3*68\n \n 142+x=204\n \n x=204-142\n \n x=62 \ in

A bag contains 90 marbles, some red and some blue. If there are 60 blue marbles, what is the ratio of blue to red marbles?

Answers

If there is a total of 90 marbles, and we know that there is 60 blue marbles. We can assume that the remaining 30 marbles are red therefore the ratio of red to red marbles would be 60÷30, which is 2. Or the ratio is 60:30 which is reduced to 2:1.
