Answer:
3 acute angles.
Step-by-step explanation:
Triangles have three angles. If any one angle is obtuse or right-angle, then the remaining two angles must be acute. Or else, all the 3 angles can be acute.
An example can be an equilateral triangle because it has 3 acute angles. Each angle is 60 degrees.
Subtract 15 on both sides and you get the answer x= -27
It would be 443 bc you would subtract by 6 2x
Pythagorean theorem
x^2 + 5^2 = 10^2
x^2 + 25 = 100
x^2 = 75
x = +sqrt(75), -sqrt(75) = +5sqrt(3), -5sqrt(3)
