Answer:
x = 5*sqrt(2)
Step-by-step explanation:
Equation
Use the Pythagorean Theorem to get the value of x. If the triangle is isosceles, it means that both lets are equal to x.
x^2 + x^2 = 10^2
2x^2 = 100
x^2 = 50
x^2 = 5 * 5 * 2
sqrt(x^2) = sqrt(5*5*2)
x = 5*sqrt(2)
There is no denominator to rationalize. The answer is given as a irrational root. The only other way to present it is in an approximate decimal form.
Answer:
Step-by-step explanation:
a is the base
b is the power
c is the root
a = 7
b = 9
c = 4
Answer:
80°
Step-by-step explanation:
The angles can be written as 4x, 6x, and 8x. Since the sum of angles in a triangle is 180 degrees we can write:
4x + 6x + 8x = 180
18x = 180
x = 10 which means the largest angle (8x) = 8 * 10 = 80°
The Answer to the question is 1.
