Two vertical angles will always equal 180 degrees

Mathematics
1 answer:
Margarita [4]3 years ago
7 0

Answer:

Hi there!

Vertical angles are angles that are opposite each other when two lines intersect each other. The two pairs of opposite angles are equal to each other. The two pairs of neighboring angles are supplementary, meaning they add up to 180 degrees.

At a certain hospital, the probability of a child being born female is 0.51. If 80 babies are born on the a certain day, the pro
Ber [7]

Answer :

0.53

Step-by-step explanation:

Given the following :

Probability of female = probability of success on a single trial = 0.51

Number of babies = 80

Probability that more than half of the babies are female : p(X >80/2) = P(X > 40)

The problem can be solved using the binomial probability function :

P(X > 40) = [ p(X= 41) + p(X= 42) +.... +p(X= 80)]

In other to save computation time, we can use the binomial probability calculator

Hence ; P(X > 40) = 0.527 = 0.53

What is 10 squared plus b squared equals 22 squared
klio [65]
I'm pretty sure you are asking for the value of b. Let's actually write it and then solve it:
10^2 + b^2 = 22^2

Solving for b yields:
b = \sqrt{22^2-10^2} = \sqrt{484-100} = \sqrt{384} = 19.59

So, b = 19.59. If you want the answer in simplified radical form, we can also do that:
\sqrt{384} =  \sqrt{16*24} = 4 \sqrt{24} = 4 \sqrt{4*6} = 8 \sqrt{6}

So, b = 8√6 = 19.59

Please explain step by step
Alja [10]

Let's find the value of x

Since the sum of internal angles of a triangle is 180°

therefore,

\hookrightarrow \: (2x - 2) \degree + (x + 5) \degree + 90 \degree = 180 \degree

\hookrightarrow \: 2x - 2 \degree + x + 5\degree  = 180\degree - 90\degree

\hookrightarrow \: 3x + 3\degree = 90\degree

\hookrightarrow \: 3(x + 1) = 3(30)

\hookrightarrow \: x + 1\degree = 30\degree

\hookrightarrow \: x = 29\degree
