Which shape has some perpendicular sides but no parallel sides?
a right triangle, a pentagon w/ a right angle, alot of shapes with right angles.
Is there an algebraic formula for determining an angle of reflection using only the angle of the ray and the angle of the wall?
Let r be the angle of the ray, and R the angle of reflection.If the wall is flat (i.e., if its angle is 0), then we know that r + R = Pi/2.Now suppose the wall has angle w. Then rotate the diagram by -w,so that the wall is now flat again, and the angles of the ray and itsreflection are now r - w and R - w, respectively.We then have (r - w) + (R - w) = Pi/2, which should give you enoughinformation to find R.
How do you work out the exterior and interior angles of a regular polygon with W sides?
Exterior angle regular polygon = 360° ÷ number of sides = 360° ÷ W Interior angle regular polygon = 180° - exterior angle regular polygon = 180° - (360° ÷ number of sides ) = 180° - (360° ÷ W)
What is a shape w 7 sides called?
A 7 sided shape is a heptagon.
What type of object has an acute angle?
objects that have an acute angle are a sideways v on a keyboard, a cheerleader w/ their arms up, and a triangle
If W is the center of the circle and arc XZ measures 52 degrees what is the measure of angle XYZ?
26 degrees
BC is one side of a regular n-gon the sides next to BC are extended to meet at W Find the measure of angle W in terms of n?
The question is not very coherent. However if the sides either side of BC are able to meet at a point, then the angle between BC and the adjacent sides must be less than 90 degrees. Hence the shape can only be a triangle and since it's regular the angle must be 60 degrees. So if n is 3, the angle (60) is 20n.
Which shape has some perpendicular sides but no parallel sides?
a right triangle, a pentagon w/ a right angle, alot of shapes with right angles.
What type of triangle has side measures of 6 cm 7 cm and W cm and one angle with a measure of 120?
It is an obtuse angled triangle.

The letter "w" has three acute angles.
What is the shape of Scotland?
W
What does the w and the t stand for on a camera?
W=WIDE or WIDE-ANGLE and T=TELEPHOTO
Is angle scalar or vector?
Almost all of us would say that angle is a scalar quantity. But the beauty is that angle is a vector quantity. Now the question arises. Where will be the direction? As we measure the angle in a plane in counter clockwise direction, then direction of angle vector will be perpendicular to the plane and coming out of the surface. If the angle is measured in clockwise then vector would go into the surface normally. As angle becomes vector then angular velocity w = @/t also becomes a vector.
