use an angle finder
the tangent of an angle is equal to the length of the opposite side from the angle divided by the length of the side adjacent to the angle.
Calculate the percentage that a particular sector represents of the total value. Then the angle size is 3.6 times the percentage.
Multiply the percentage by 3.6
A roof angle of 6 degrees = 1.26 / 12 rise or pitch.

Vertebral Foraminal Entrapment on Hip Flexion and Knee Extension
Frontal Plane about the anterioposterior axis
hip flexion and hip extention
The prim mover for hip flexion is the Rectus femoris. This is a quadricep muscle that crosses the hip joint.
Flexion is movement during which the knees or elbows are bent to decrease the angle of the joint
rectus femoris
Pectineus
The optimal angle for shoulder flexion to achieve a 90-degree angle is approximately 150 degrees.
The primary antagonist for hip flexion is the gluteus maximus, as it functions to extend the hip joint. Additionally, the hamstring muscles, particularly the semitendinosus, semimembranosus, and biceps femoris, also play a role in opposing hip flexion. When the hip flexors contract to lift the thigh, these muscles act to control or resist that movement.
