Using
sum = (n-2)180
= (15-2)180 = 13×180 = 2340°
Answer:
no because thats an obtuse angle and there has to be an acute triangle to from a triangle so no

Subtracting numbers is one of the basic operations in math.
Firstly, the order of operations is as follows: PEMDAS or parentheses, exponents, multiplication, division, addition, then subtraction.
All of these are done in the exact order given above.
For example, given the equation (4 x 7) + (6 / 2) - 3^2 = ?
1. Parentheses
- Solve the equations within the parentheses first.
(4 x 7) + (6 / 2) - 3^2 = 28 + 3 - 3^2
2. Exponents
- Second, if there are any exponents, solve this.
28 + 3 - 3^2 = 28 + 3 - 9
3. Mulltiplication
4. Division
5. Addition
28 + 3 - 9 = 31 - 9
6. Subtraction
31 - 9 = 22
Answer: 22.

Answer:
P(R) = 0.14
P(I) = 0.16
P(D) = 0.315
Step-by-step explanation:
Let Democrat = D
Republican = R
Independent = I
If 45% are Democrats, 35% are Republicans, and 20% are independents, then
Total registered voters = 100
In an election, 70% of the Democrats, 40% of the Republicans, and 80% of the independents voted in favor of a parks and recreation bond proposal. That is,
D = 0.7 × 45 = 31.5
R = 0.4 × 35 = 14
I = 0.8 × 20 = 16
If a registered voter chosen at random is found to have voted in favor of the bond, what is the probability that the voter is
a Republican:
P(R) = 14 /100 = 0.14
an Independent
P(I) = 16/100 = 0.16
a Democrat
P(D) = 31.5/100 = 0.315
