3x - 20 + 3x + 5 = 111

Combine like terms
6x - 15 = 111

Add 15 to each side.

Evaluate
6x = 126
x = 21

Plug x back into the equation for angle EFG.
EFG = 3x -20
3(21) - 20
EFG = 43 degrees

Answer:

[tex] m\angle EFG =43\degree[/tex]

Step-by-step explanation:

[tex] m\angle EFG +m\angle GFH = m\angle EFH\\\\

(3x-20)\degree + (3x+5)\degree =111\degree \\\\

(3x-20+3x +5)\degree =111\degree \\\\

(6x-15)\degree =111\degree \\\\

(6x-15) =111 \\\\

6x = 111 + 15\\\\

6x = 126\\\\

x = \frac{126}{6}\\\\

x = 21\\\\

m\angle EFG = (3x-20)\degree\\\\

m\angle EFG = (3\times 21-20)\degree\\\\

m\angle EFG = (63-20)\degree\\\\

m\angle EFG =43\degree\\[/tex]

Answers

Answer:

D

Step-by-step explanation:

I used a triangle calculator I'm not really sure how to calculate it by hand. if the angle of sides 4 and 15 is set to 1 then the min is 11.33 and if the andle of sides 4 and 15 are set to 179 then the max is 18.99952

Sorry if this isnt enough, but i am sure.

Answer:

D.  11 < x < 19.

Step-by-step explanation:

The third side x is between 11 and 19 cm.

Consider sides AB (length 4) and BC (length 15) of the triangle.

Consider the angle between AB and BC is slightly less than 180 degrees.  To get from point A to point C, we have to travel almost the entire length of A to C, which is from A to B and then B to C, so a bit less than 19 cm.

Consider the angle between AB and BC is slightly more than 0 degrees.  To get from point A to point C, we subtract the length of AB (because we're already further along BC), so 15 - 4, a bit greater than 11.

Answer:

B. To determine the percent of adults in the country who believe the federal government wastes 51 cents or more of every dollar.

Step-by-step explanation:

Given that:

sample size = 1026

sample proportion = 0.36

Margin of error = 55% = 0.55

Confidence interval level = 99%

The purpose of this question is to determine the research objective:

The research objectives indicate the intention of the study, the objectives,\ or the main idea. This main idea arises from a need (the research problem) and refined into specific questions (i.e. the research questions). From, the given information, the research objective is to determine the percent of adults in the country who believe the federal government wastes 51 cents or more of every dollar.

GEOMETRY QUESTION, HELP PLEASEEE.

Answers

Answer:

The pre-image C is (2, 5)

Step-by-step explanation:

If the point (x, y) rotated about the origin by angle 90° clockwise, then its image is (y, -x)If the point (x, y) rotated about the origin by angle 180° clockwise, then its image is (-x, -y)If the point (x, y) rotated about the origin by angle 270° clockwise, then its image is (-y, x)

∵ Point C was rotated 270° clockwise around the origin

∵ C' = (-5, 2)

→ By using the 3rd rule above

∵ The image of the point (x, y) is (-y, x)

∴ (-y, x) = (-5, 2)

→ That means -y = -5 and x = 2

∴ x = 2

∴ -y = -5

→ Divide both sides by -1

∴ y = 5

∴ The pre-image C = (2, 5)

Answer:

Expand the brackets, and simplify.

(4t - 8/5)-(3-4/3t) = (4t +4/3t) + ( -8/5 - 3) = 5 1/3t - 23/5 = 16/3t - 23/5

5(2t + 1) + (-7t + 28) = 10t + 5 - 7t + 28 = 3t + 33

(-9/2t + 3) + (7/4t + 33) = (-9/2t + 7/4t) + (3 + 33) = -11/4t + 36

3(3t - 4) - (2t + 10) = 9t - 12 - 2t - 10 = 7t - 22
