Answer:
3
Step-by-step explanation:
Answer:
The correct option is;
The sum of angles A and B are supplementary to angle C
Step-by-step explanation:
The statements are analysed as follows
1. Angle A is congruent to itself reflective property
Which shows that ΔABC and ΔADE have a common and equal angle
2. Segment ED and CB are parallel
From the transversal line passing EB and CB which shows that the angles ∠ADE and ∠ABC are equal and also ∠AED and ∠ACB are equal
The statement is used to prove similarity between the ΔABC and ΔADE
3. The sum of angles A and B are supplementary to angle C
The above statements relates to only ΔABC and i does not show similarity between ΔABC and ΔADE.
Magnitude is sqrt ( -sqrt2/2 ^2 + -sqrt2/2 ^2)
= sqrt (0.5 + 0.5)
= 1
The vector is in the third quadrant and its tangent = 1 so the angle is 180 + 45
= 225 degrees
It has to be b because you put it in a calculator and it does it right for you
