Answer:

115°

Step-by-step explanation:

The above shape is a quadrilateral.

A quadrilateral is a closed shape and a type of polygon that has four sides, four vertices and four angles.

The sum of interior angles of a Quadrilateral is 360°

Therefore,

115 + 65 + 65 + m = 360

245 + m = 360

m = 360 - 245

m = 115°

Therefore, m< B = 115°

I need help with this

Alex787 [66]

The area of a triangle is 1/2(base)(height) and since this is a right triangle the two legs can be base and height. So the area is 1/2(2x-4)^2 which becomes 1/2(4x^2-16x+16) which is simplified to 2x^2-8x+8. B is the correct answer.
