Answer:
B. C is parallel to D.
Step-by-step explanation:
since lines 1 and 3 are congruent it means they have the same shape and size, They lie in the same plane and they are both lines. However lines 1 and 3 which is C and D never intersect, therefore they are parallel.
Answer:
70° and 20°
let the other 2 angles be 7x and 2x
90+7x+2x=180
9x=180-90
x=90/9
x=10
7x=7x10
70
2x=2×10
2p
Answer:
A
Step-by-step explanation:
3x^2 - 8x + 4 = 0
x= [-b +or- square root (b^2 - 4ac)] ÷ 2a
= [-(-8) +or- square root (-8)^2 - 4(3)(4)] ÷ 2(3)
= [8 +or- square root 16] ÷ 6
= 2 or 2/3
The distance between point C and point D is 10.
Point D is on the 1 and Point C is on -9.
1-(-9)=10.
