When first red drawn =2/10=1/5
When second drawn it is going to be 1/9, because one red was removed, so only one left, and altogether is 9 now
P(red, then red)=1/5 *1/9= 1/45
Answer:
A
Step-by-step explanation:
5x and 128 are adjacent angles and sum to 180° , then
5x + 128 = 180 ( subtract 128 from both sides )

x = 10.4 → A
Answer: C - the fourth month

<em>P = 10a + 68 cm</em>
- <em>Step-by-step explanation:</em>
<em>Hi there !</em>
<em>P = 2w + 2l</em>
<em>= 2(2a - 34) + 2(3a + 75)</em>
<em>= 4a - 68 + 6a + 150</em>
<em>= 10a + 68 cm</em>
<em>Good luck !</em>
Answer:
Step-by-step explanation:
You can use SOH or CAH to find one of the sides
and then just a²+b²=c² to find the last one
