Examine the diagram. A triangle. Angle B is the exterior angle to angle A. The other 2 exterior angles are 100 degrees and 127 degrees. Follow these steps to apply what you have learned about the angles of a triangle. Find m∠B : 100° + 127° + m∠B = 360° Then, find the measure of angle A. Which is the measure of angle A? 133° 53° 47° 80°

hey um this isn't an answer but do you know the answer to this

Step-by-step explanation:

Arnold is planning on painting a mural. Before painting the mural, Arnold painted the picture on a paper that is 5 inches wide and 11 inches tall. Arnold is using a scale in which 1/2 inch represents 1 foot to paint the mural.

How tall will the actual mural be?

How wide will the actual mural be?

Separating your figure into two separate parts would solve this problem.let's start with the square first. each of the sides of the square is 4 yards long. to find the area of a square, use the formula  a =   (area = side).a =  a = 16 next, we'll find the area of the triangle. the formula for the area of a triangle is  a =  bh (area =  base x height). the height of your triangle is made up of two 4 yard segments. the total for the height would then be 8 yards (4+4).a = (6  · 8)a = (48)a = 24 ydlet's combine to find the total area of the entire figure.square = 16 triangle = 24 ydadding them together, the total area will give you an answer of 40 yd.
