The other two angles are 72 degrees and 32 degrees respectively.

72 + 32 = 104 so the total of the two known angles is 104 degrees.

All triangles add up to 180 degrees.

180 - 104 = 76, so be is equal to 76 degrees.

ipn [44]

Answer:

<h2>2/5</h2>

Step-by-step explanation:

The question is not correctly outlined, here is the correct question

<em>"Suppose that a certain college class contains 35 students. of these, 17 are juniors, 20 are mathematics majors, and 12 are neither. a student is selected at random from the class. (a) what is the probability that the student is both a junior and a mathematics majors?"</em>

Given data

Total students in class= 35 students

Suppose M is the set of juniors and N is the set of mathematics majors. There are 35 students in all, but 12 of them don't belong to either set, so

|M ∪ N|= 35-12= 23

|M∩N|=  |M|+N- |MUN|= 17+20-23

           =37-23=14

So the probability that a random student is both a junior and social science major is

=P(M∩N)= 14/35

=2/5

340 yards increased by 145% is how many yards? Can you please show me how you got your answer.
Studentka2010 [4]
Just turn the percentage to a decimal. 145% becomes 1.45. Then add 1.00 to 1.45. 1 + 1.45 = 2.45

Then multiply. 2.45 * 340 = 833

Find the missing part. Find Px
MariettaO [177]
Px = missing length
xy = 3
Py = 6
these are the 3 sides of a right triangle; let's use the Pythagorean theorem to find Px
(Px)² + 3² = 6²  subtract 3² from both sides
(Px)² = 36 - 9 simplify the right
(Px)² = 27 take the square root of both sides
Px = \sqrt{27}
Px = 3 \sqrt{3}
