<span>2x+38=180 since all triangles add up to 180 and we have 38 as a degree we have to find the value of
2x=180-38
2x=142
x=142÷2
x=71</span>
In radians:
To get 0, only one part of the multiplication needs to be zero for the whole thing to be zero. Thus we get 2 equations:
t=0, and cos(t)=0
for the first equation, it's pretty self-explanatory and sp we get 0 as one solution.
For the second equation, cos(pi/2) and cos(3pi/2) both equal 0 so both pi/2 and 3pi/2 are answers. Since there is no bound to this problem, the actual answer is:
(2Z+1)pi/2 and 0
(2Z+1) means all odd integers
Answer:
11.
Step-by-step explanation:
I think that is the answer. If so mark brainliest pls

<h2>The required probability is

.</h2>
Step-by-step explanation:
In the urn, there are total (7 + 8 + 9) = 24 balls.
We are taking 10 balls out of the urn with replacement.
In each tern, we have overall 10 choices to chose 1 ball.
If we <u>want to get a green</u>, there are 7 choices each time.
Similarly, 8 choices each time for getting a red and 9 choices each time for getting a yellow ball.
The probability of getting green 2 times, red 3 times, and yellow 5 times is
