If H is in the interior of ∠EFG, m∠EFH = 75°, and m∠HFG = (10x)°, and m∠EFG = (20x − 5)°, then x = ? and m∠HFG = ?
Diano4ka-milaya [45]

Answer:

x=8

\m\angle HFG= 80^\circ

Step-by-step explanation:

Given that:

Point H is interior of \angle EFG.

m\angle EFH = 75^\circ\\m\angle HFG = (10x)^\circ\\m\angle EFG = (20x-5)^\circ

To find:

x = ?\\m\angle HFG = ?

Solution:

First of all, let us represent the given values in the form of a diagram.

Kindly refer to the attached image for the given points and values of angles.

We can clearly see that:

m\angle EFG = m\angle EFH + m\angle HFG

Putting all the values given in above equation, we get:

(20x-5)^\circ = 75^\circ + 10x^\circ\\\Rightarrow 20x-10x=75+5\\\Rightarrow 10x =80\\\Rightarrow \bold{x =8}

m\angle HFG =10x^\circ\\\Rightarrow m\angle HFG =10\times 8^\circ\\\Rightarrow m\angle HFG = \bold{80^\circ}

What is an equation of the line that passes through the points (3,4) and (−4,−3)? Put your answer in fully reduced form
sasho [114]

Answer:

The equation of the line is y = x + 1

Step-by-step explanation:

The equation of the line is y = m x + b, where

  • m is the slope of the line
  • b is the y-intercept

The rule of the slope of the line is m = \frac{y2-y1}{x2-x1} , where

  • (x1, y1) and (x2, y2) are two points on the line

∵ The line passes through points (3, 4) and (-4, -3)

∴ x1 = 3 and y1 = 4

∴ x2 = -4 and y = -3

→ Substitute them in the rule of the slope above to find it

∵ m = \frac{-3-4}{-4-3} = \frac{-7}{-7} = 1

∴ m = 1

→ Substitute it in the form of the equation above

∴ y = 1(x) + b

∴ y = x + b

→ To find b substitute x by 3 and y by 4 in the equation

∵ 4 = 3 + b

→ Subtract 3 from both sides

∵ 4 - 3 = 3 - 3 + b

∴ 1 = b

→ Substitute it in the equation

∴ y = x + 1

∴ The equation of the line is y = x + 1

Which of the following would be appropriate to measure in centimeters? the distance between Philadelphia and New York City, the
iren [92.7K]

To measure the length or height of something which is a little smaller we prefer to use centimeters.

Lets look at each of the options one by one.

1. Distance between Philadelphia and New York , it is roughly about 94.1 miles which will be way too big of a number if converted in to centimeters (it will be 15000000 cm).

2. Length of a paperclip, this is something that is a considerable length and can be measured in centimeters. Usually a paper clip measures around 3-4 centimeters.

3. Height of a standard ceiling, while constructing something we measure height or length or the width of a floor in feet.

4. Yearly increase in a child's height, that can be measured in centimeters but often we use inches.

5. Width of a swimming pool is also conventionally measured in feet.

So, it is the length of a paperclip and the yearly increase in a height of a child are two things that can be measured in centimeters.

In a survey, 300 shoppers were asked whether they have access to a computer at home and if they have a personal e-mail account.
Tamiku [17]

Answer:

A. 64%, B. 62%

Step-by-step explanation:

Find how many people do not have an email account.

168 + 24 = 192 Find the percentage.

192/300 = 0.64 Hence, 64% of shoppers don't have an email.

Do the same for B.

168 + 18 = 186

186/300 = 0.62

62% of shoppers don't have access to a computer.
