FIRST PROBLEM AS GENIUS!!!
The 45-45-90 triangle theorem states that each leg equals x, and the hypotenuse equals
. Using this, we can find that the height is 10. Take the average of the lengths to get l = 27.
The area = 270.
The 45-45-90 triangle theorem states that each leg equals x, and the hypotenuse equals
The area = 270.
Answer:
Base of triangle is 9 inches and altitude of triangle is 14 inches.
Step-by-step explanation:
Given:
Area of Triangle = 63 sq. in.
Let base of the triangle be 'b'.
Let altitude of triangle be 'a'.
Now according to question;
altitude is 5 inches longer than the base.
hence equation can be framed as;
Now we know that Area of triangle is half times base and altitude.
Hence we get;
Substituting the values we get;
Now finding the roots for given equation we get;
Hence there are 2 values of b
Since base of triangle cannot be negative hence we can say
So Base of triangle = 9 inches.
Altitude = 5 + base = 5 + 9 = 14 in.
Hence Base of triangle is 9 inches and altitude of triangle is 14 inches.
