Answer:
Same-side Interior Angles theorem justifies ∠ 11 + ∠ 10 =180°
Step-by-step explanation:
To Prove:
∠ 11 + ∠ 10 =180°
Proof:
Consider lines are Parallel,then
Corresponding Angles are Equal
∴ ∠ 10 = ∠ 12 say (equation 1)
Now by Linear Pair postulate we have,
∴ ∠ 11 + ∠ 12 = 180° say (equation 2)
Now by replacing ∠12 by ∠ 10 from equation 1 in equation 2 we get
∴ ∠ 11 + ∠ 10 = 180°
Hence proved the above statement.
Answer:
Option (3)
Step-by-step explanation:
Option (1).
AB and SE are coplanar.
Incorrect.
AB lies in a plane ABS and SE lies in another plane SEL.
Option (2).
TS and SE intersect at E.
Incorrect.
They intersect at S.
Option (3).
R intersects K at SB.
Correct.
Since line of intersection of planes R and K is SB
Option (4)
AB and BL are perpendicular at B.
Incorrect.
Angle between them is not 90°.
Answer: the answer is 20,250
Step-by-step explanation:
35% of 15,000 = 5,250
15,000+5250 = 20,250
Point slope form : y-y1 = m(x-x1)
slope intercept form : m=(y-y1)/(x-x1)
standard form : Ax + By = C
just pick any random points on a graph and plug the same points into all three forms.
distance = rate * time
2.56 meters = 2meter/min * t
divide by 2 on each side
2.56/2 =t
1.28 minutes =t
