Day 1 Practice 6: Find The Angle Measure Of Angle A,C,B

Answers

Answer 1

Answer:

Angle A: 60

Angle B: 30

Angle C: 90

Step-by-step explanation:

To figure out the angles, you need to set up an equation:

180 = x + x + 30 + x + 60

Add like terms:

180 = 3x+ 90

Solve for x

90 = 3x

divide by 3 to get x

30 = x

So, x is 30, and angle a is angle b plus 30, which is 60. angle c is x plus 60, which is 90.

The standard deviation is 2.08.

What is Standard Deviation?

A standard deviation (or σ) is a measure of how dispersed the data is in relation to the mean. Low standard deviation means data are clustered around the mean, and high standard deviation indicates data are more spread out.

We have the data,

X     :   0     1     2     5     10

P(X) :  0.4  0.2  0.2  0.1  0.1

CF   : 0.4   0.6  0.8  0.9  1

Sum of fx = 2.5

Mean = 2.5

Deviation X = -2.1 -2.3 -2.1 -2 -1.5

X² = 4.41 5.29 4.41 4 2.25

fX² = 1.764 1.058 0.882 0.4 2.225

Now, standard deviation

= √4.329/1

= 2.08

All three angles on a triangle always equal 180°.

Example: 100°+40°+40°=180°

102+39=141°

180-141=39°

x = 39°

You add both the numbers up and see what they get. Then you subtract that number from 180 since that is always what a triangle equals, therefore your answer is 39

Answers

Responder:

Explicación paso a paso:

Tres números naturales consecutivos:

Número medio = m

Los otros dos números son; m - 1; m + 1

Por tanto, tenemos:

m - 1, m, m + 1

Cuadrado de m = (m - 1) + (m + 1) + 15

m² = 15 + (m - 1 + m + 1)

m² = 15 + (m + m)

m² = 15 + 2m
