Answer:
b=23 degrees
Step-by-step explanation:
a was 66 degrees so b=23 degrees 180-90-66=23
Answer:
Hello! answer: 9
Step-by-step explanation:
Assuming this is a complementary angle (meaning it will add up to 90 degrees)
5 × 9 = 45 45 + 15 = 60 60 + 30 = 90 therefore x = 9 Hope that helps!
A, B and E.
Adding and multiplying the terms allow them to keep working. However, you must make sure that each variable is changed each time. Not just one as in C and D.
About how many pages.....estimate : 70 + 80 = 150
actual : 72 + 83 = 70 + 80 + 5 = 155
There are 52 cards in a deck.
First we find the probability of drawing a 2
There are 4 cards that shows 2
Probability of drawing a 2 card fro 52 cards = 4 / 52
We know that P( not A) = 1 - P(A)
So the probability (not dealt a 2) = 1 - probability (dealt a 2)
= 1 - 4/52
= (52 - 4)/ 52 = 48/52
Now we simplify the fraction
48/ 52 = 12/13
Hence, the probability( not dealt a 2) = 12/13
