In general, the sum of the measures of the interior angles of a quadrilateral is 360. This is true for every quadrilateral. This does not help here, because there are two angles (angles B and D) we know nothing about. We only know about opposite angles A and C.
In this case, you can use another theorem.
Opposite angles of an inscribed quadrilateral are supplementary.
m<A + m<C = 180
3x + 6 + x + 2 = 180
4x + 8 = 180
4x = 172
x = 43
m<A = 3x + 6 = 3(43) + 6 = 135
Answer: 135 deg
Answer:
3.14
Step-by-step explanation:
A=π*r^2
3.14*(2^2)
3.14*4
12.56/4 (because it's 1/4th a circle)
3.14.
I believe it’s B . Not 100 percent sure but yeah
Answer:
P(x > 10) = 0.6981.
Step-by-step explanation:
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

In which
is the number of different combinations of x objects from a set of n elements, given by the following formula.

And p is the probability of X happening.
In this question:

P(x>10)

In which






So P(x > 10) = 0.6981.
I'll give you a hint. <u><em>This questions is about order of operations for pemdas. Its stand for: p-parenthesis, e-exponents, m-multiply, d-divide, a-add and s-subtract that came from left to right.</em></u>
First you had to calculate with exponents first.


Then you multiply and divide from left to right.





Final answer: 
Hope this helps!
And thank you for posting your question at here on brainly, and have a great day.
