This is hard, but i really need !
a triangle has two given sides, one is 5 in and the other is 10 in. what would the third side have to be for the triangle to be an:
1.) acute triangle
2.) obtuse triangle
comment if you have any questions! : )

What two criteria are needed for triangles to be similar

Which statements are true? check all that apply. the line x = 0 is perpendicular to the line y = –3. all lines that are parallel to the y-axis are vertical lines. all lines that are perpendicular to the x-axis have a slope of 0. the equation of the line parallel to the x-axis that passes through the point (2, –6) is x = 2. the equation of the line perpendicular to the y-axis that passes through the point (–5, 1) is y = 1.

Can someone, me with this.i really need with this
