If c=12 find a right triangle 90 degrees 45 degrees 45 degrees

Answers

Answer 1
Answer:

If is a triangle 90°, 45°, 45° then the sides are in ratio 1 : 1 : √2.

If c = 12 is a hypotenuse, therefore we have the equation:

a\sqrt2=12\ \ \ \ |\cdot\sqrt2\n\n2a=12\sqrt2\ \ \ \ |:2\n\n\boxed{a=6\sqrt2}

If c = 12 is a leg, therefore we have:

\boxed{a=12\sqrt2}

If x=5 and the area of the rectangle is 30 what is the other length of the rectangle?

Answers

Answer:

The other length would be 6.

Step-by-step explanation:

Rectangle area is l times height. So x is either the length for height. So we have 5 times x = 30. To find the other length we have to take 30/5 which equals 6

Find x when y =18, if y = 5 when x = 4
