Find the Missing Angle)
Answer:
110-degrees
Step-by-step explanation:
these are alternate exterior angles which are equal *congruent
Answer:
Since 110° and ? are alternate exterior angles, take the 110° and subtract 180°. Remember, 180° is a straight angle. So, 180°-110°= 70°.
The missing angle is 110°, I just solved for the remaining angle to help you figure it out more easily.

A. 84 feet
B. 60 feet
C. 6 feet
D. 864 feet

Eight friends want to play enough games of chess to be sure everyone plays everyone else. How many games will they have to play?
The number of games, the friends have to play is an illustration of combination.
They have to play 28 games to ensure that they all play
Given
[tex]n = 8[/tex] --- number of friends
[tex]r = 2[/tex] --- only two friends can play at a time
For everyone else to play, we will make use of the following combination formula;
[tex]^nC_r = \frac{n!}{(n - r)!r!}[/tex]
So, we have:
[tex]^8C_2 = \frac{8!}{(8 - 2)!2!}[/tex]
[tex]^8C_2 = \frac{8!}{6!2!}[/tex]
Expand
[tex]^8C_2 = \frac{8 \times 7 \times 6!}{6! \times 2 \times 1}[/tex]
[tex]^8C_2 = \frac{8 \times 7}{2 \times 1}[/tex]
[tex]^8C_2 = 4 \times 7[/tex]
[tex]^8C_2 = 28[/tex]
Hence, the 8 friends have to play 28 games to ensure that everyone else plays

Answer:
[tex]x=2.05[/tex]
Step-by-step explanation:
To solve this problem, use the trigonometric ratios. The trigonometric ratios for a right triangle (a triangle with a right angle are the following).
[tex]sin(\theta)=\frac{opposite}{hypotenuse}\\\\cos(\theta)=\frac{adjacent}{hypotenuse}\\\\tan(\theta)=\frac{opposite}{adjacent}[/tex]
In this case, one is given the hypotenuse (the side opposite the right angle) and one is asked to find the side adjacent to the given angle. Therefore, it would make the most sense to use the trigonometric ratio of cosine ([tex]cos[/tex]).
[tex]cos(\theta)=\frac{adjacent}{hypotenuse}[/tex]

Now,
Because it does not have an equal sign. It can be written as L + 6, where L is the number of minutes that Laura sang.
The sentence “Ken sang 6 minutes longer than Laura” is a situation that can be modeled by an equation, because it involves a relationship between two quantities. It can be written as K = L + 6, where K is the number of minutes that Ken sang and L is the number of minutes that Laura sang.

What is the area of the shaded Region? (Answer to the Nearest Tenth)
Shaded area = Circle area - Rectangle area
Shaded area = 3.14 × (4)^2 - 5 × 6
Shaded area = 3.14 × 16 - 30
Shaded area = 50.24 - 30
Shaded area = 20.24

Answer:
23) x=20; y=10√3
24) x=4√2; y=8
25) x=12; y=3+6√3
Step-by-step explanation:
Recognize that all of the triangles involved here are one of the two "special" triangles. By previous use of the Pythagorean theorem, or your familiarity with the trig functions of the "special" angles 30°, 45°, 60°, you know the following side ratios:
45°-45°-90° triangle: 1 : 1 : √2
30°-60°-90° triangle: 1 : √3 : 2
Using these ratios, you can solve these figures "by inspection."
__
23) x = 2((10√2)/√2) = 20
y = √3((10√2)/√2) = 10√3
__
24) x = 4√2
y = (4√2)√2 = 8

25) x = 6·2 = 12

Solve:
2^x-3= 1/8
(and if you can, put a step by step. you don't have to though)
Answer:
[tex]x = 0[/tex]
Step-by-step explanation:
Write the number in exponential form with the base of 2:
[tex] {2}^{x - 3} = {2}^{ - 3} [/tex]
Since the bases are the same, set the exponents equals.
[tex]x - 3 = - 3[/tex]
Cancel equal terms on both sides of the equation:
[tex]x = 0[/tex]
[tex]2 {}^{x - 3} = \frac{1}{8} [/tex]
To Find value of 'x'
Solution[tex]2 {}^{x - 3} = \frac{1}{8} \\ \\ \implies2 {}^{x - 3} = 2 {}^{ - 3} \\ \\ \\ Since \: Bases \: Are \\ Equal \: We \: Need \\ To \: Evaluate \\ The \: Powers \\ \\ \implies \: x - 3 = - 3 \\ \\ \implies x = - 3 + 3 \\ \\ \implies \: x = 0[/tex]

What is the value of x? (3x + 50) Enter your answer in the box (6x - 10) X =
Answer:
x = 20
Step-by-step explanation:
(6x - 10) and (3x + 50) are vertical angles and are congruent, then
6x - 10 = 3x + 50 ( subtract 3x from both sides )
3x - 10 = 50 ( add 10 to both sides )
3x = 60 ( divide both sides by 3 )
x = 20

A fireman leaned a 28 foot ladder against a building. If he placed the ladder 14 feet from the base of the building, what angle is formed between the ladder and the ground
Answer:
The ladder makes an angle of 60 degree from the ground.
Step-by-step explanation:
Length of the ladder, L = 28 feet
distance of ladder, d = 14 feet
Let the angle formed with the ground is A.
According to the trigonometry
[tex]\cos A =\frac{d}{L}[/tex]
[tex]\cos A =\frac{14}{28}[/tex]
cos A = 0.5
A = 60 degree
On the way home from her friend's house Sandy skateboards 30% of the way, walks 1/2 of the way, and then skips the rest of the way. Which decimal number shows the portion of the distance Sandy skips?
Answer:
0.2
Step-by-step explanation:
Convert the walking to percent
[tex]\frac{1}{2} \times 100 = 50[/tex]
Add both skateboarding and walking
[tex]30\% + 50\%\\\\= 30 + 50\\\\= 80[/tex]
Now, subtract that from a whole percent
[tex]100 - 80 = 20\\\\20\%[/tex]
Convert it to a decimal
[tex]20\% = \frac{20}{100} \\\\=20 \div 100\\\\= 0.2[/tex]
Therefore, in decimal, 0.2 is the number that shows the portion of the distance Sandy skips.
