Answer:
The probability of the first draw is 100%, because the bead will be either red or white. For the second draw, a different color must be drawn.
So, if draw 1 is white, then the probability of draw 2 being red is 7/10. and if the first draw is red, then the probability of draw two being white is 5/10.
first get all variables on the same side, then use elimination to solve.
x = -3
y = -11
Answer:
73,58,107,49,131
Step-by-step explanation:
m∠1=73°because alternate interior angles
m∠2= 180-49-73=58° because straight lines make 180° angles
m∠3=58+49=107° because alternate interior angles
m∠4 =49° because alternate interior angles
m∠5=180-49=131° because straight lines make 180° angles
