Answer:
U = 48
Step-by-step explanation:
The sum of the angles of a triangle add to 180 degrees
x+21 + x+23 + x+61 = 180
Combine like terms
3x + 105 = 180
Subtract 105 from each side
3x+105-105 = 180-105
3x = 75
Divide by 3
3x/3 = 75/3
x = 25
We want angle u
x+23
25+23
48
Answer:
P(blue then red)=5/169
Step-by-step explanation:
the probability of picking the blue is 4/26 it's replaced so the total jellybeans doesn't change therefore the sample space doesn't change. the probability of picking a red is 5/26
to find the probability of picking them in that order, you multiply the two together
(4/26)x(5/26)=20/676
reducing that we get:
P(blue then red)=5/169
