Answer:

Measures of all angles is either 77.5° or 102.5°

Step-by-step explanation:

See the attached figure.

As shown:

line a parallel to line b with transversal m

So, all the angles are either congruent or supplementary.

Let the supplementary angles x and y and y > x

x + y = 180° ⇒ (1)

one angle is 25° bigger than another

y - x = 25° ⇒ (2)

solving (1) and (2)

∴ x = 77.5° and y = 102.5°

the sum of present ages ofa father and his son is 60years .if both of them live until the son becomes as old as the father is no

Nikitich [7]

I might be wrong but you tell me,

The father is 60 years old.

Son lives to be 60.

Total is 120.

Both die at the age of 60.

Could the son have been a newborn?

Idk. I don't understand it.

Wait, sum of present ages is 60. The son has to be younger by at least 20. Double it again. No, even then newborn is 0 and then 60= 60. Son lives toll he's 60 and dies, 120. Sorry, I tried. What are your possible choices?

What is the solution to the inequality?<br><br> −4x−8>−20<br> pls hurry

Sergeu [11.5K]

Answer:

x < 3

Step-by-step explanation:

−4x−8>−20

Add 8 to each side

−4x−8+8>−20+8

-4x> -12

Divide each side by -4, remembering to flip the inequality

-4x/-4 < -12/-4

x < 3

When the results of experimentation or historical data are used to assign probability values, the method used to assign probabil

wel

Answer:

Relative Frequency Method

Step-by-step explanation:

If I carry out an experiment involving 25 throws of a coin and I obtain 13 Heads(H), the Relative Frequency of obtaining Heads will be 13/25.

Now if I intend to find out approximately how many Heads will

occur in 300 throws, I simply use the result or experimentation data that I have.

This is done below:

Relative Frequency of Obtaining a Head= 13/25 =0.52

Number of Heads obtained in 300 throws

= Relative Frequency X Number of Trials

=0.52 X 300

=156

This is an example of how relative frequency method works.

The diagram shows a logo made from 3 circles.

Cloud [144]

Answer:

% area of the shaded region = 33%

Step-by-step explanation:

Radius of the middle circle = 7 cm

Radius of the inner circle = 4 cm

Area of the middle circle = πr²

= π(7)²

= 49π

Area of the inner circle = π(4)²

= 16π

Area of the shaded region= 49π - 16π

= 33π

Area of the outermost circle = π(10)²

= 100π

% area of the shaded region = $\frac{\text{Area of the shaded region}}{\text{Area of the inner circle}}\times 100$

= $\frac{33\pi }{100\pi }\times 100$

= 33%

Therefore, area of the shaded region is 33% of the complete logo.
