Answer:
135.1 cm
Step-by-step explanation:
The Pythagorean theorem tells you how to find the hypotenuse of a right triangle with legs 120 and 62:
diagonal = √(120² +62²) = √18244 ≈ 135.07
The length of one of the braces is about 135.1 cm.
x⁴ + x = 0
x(x³) + x(1) = 0
x(x³ + 1) = 0
x = 0 or x³ + 1 = 0
- 1 - 1
x³ = -1
x = -1
A all angles have equal measure
8(3+5)...they have the same factor which is 8..check
