We have a transversal across parallel lines so we get the usual array of congruent and supplementary angles. We just have to figure out which is which, and the diagram, even though not to scale, makes it pretty obvious.
Angle x isn't the same as the 40° angle so it must be its supplement.
Answer: C 140°
3.
r=1.2, h=2.9, V = (1/3) πr²h
Nothing hard here, we just plug in the numbers,
V = (1/3) π (1.2)² (2.9) ≈ 4.37310
Answer: B. 4.4 cubic inches
4.
Dilation by .5 makes a similar triangle, and reflection is an isomorphism (i.e. it doesn't change the size or shape) so the answer is
Answer: B similar not congruent
5.
The corresponding interior and exterior angles of a triangle form a linear pair, so supplementary angles. x=180-110 = 70°
Answer: A 70°
PEMDAS states to do what's in the parenthesis first...
PEMDAS states to multiply 5 by 1 next...
PEMDAS states to subtract 4 by 5 next...

Answer:
C-10
A-90
B-10
Step-by-step explanation:
For rounding off to nearest tens, we compare the last digit.
The angle adjacent to angle 3 = 45 The figure is a kite and the long diagonal cuts the top angle in 2 Therefore < 3 = 45 degrees.
Answer:
(X+3)(x+2)(x-1)(x-30)
Step-by-step explanation:
Haven’t done this in a while so I may be incorrect but that’s factored form
