Answer:
40 degrees
Step-by-step explanation:
because angle b and angle a are vertical angles they are congruent and if they add up to 280 you just have to divide that by 2 to get the value of one of the angles
280/2=140
because angle c and angle b are supplementary they are going to add up to equal 180
180-140=40 so c=40
Answer:
1. all side must intersect exactly two others sides but only at their endpoints
2. The sides must be non collinear and have a common endpoint
3. All sides must be a line segment
Answer:
Answer D is the correct answer 4x+1
Substitute in f(x) every time you see an x value in g(x)
Hence, g(f(x)) = (4x - 1)^2 + 7
= 16x^2 - 8x + 1 + 7
= 16x^2 - 8x + 8 (ie A)
