What angle will a 5 m ladder make with a wall if it reaches 4.2 m up the wall?

The angle of a triangle are given as 6x,(x-3), and (3x+7). find x then find the measures of the angles

Angle xyz is formed by segments xy and yz on the coordinate grid below: a coordinate plane is shown. angle xyz has endpoints at 3 comma negative 1 and 6 negative 2 and 3 comma negative 3 and measures 36.87 degrees. angle xyz is rotated 270 degrees counterclockwise about the origin to form angle x′y′z′. which statement shows the measure of angle x′y′z′?

Which describes the difference between the graph of f(x)=x^2 and g(x)=-(x^2-2)
