Help Please and NO LINKS!!! use trig to find the angles
mark as brainllest if its right
Answer:
x = 46.7°
Step-by-step explanation:
We are given:
1.) Angle x
2.) Side opposite to angle x
3.) Hypotenuse
We have to find angle x, therefore Sin ratio would be used;
Sin(x) = Opposite / hypotenuse
Sin(x) = 4 / 5.5
x = Sin⁻¹(4/5.5)
x = 46.7°

There were 400 students in attendance. 51% are boys. How many are boys (show your work)
Answer:
204 out of 400 students are boys; 204
Step-by-step explanation:
x/400 = 51/100
100x = 51 x 400
100x = 20400
100x/100 = 20400/100
x = 204

how many questions out of 42 do I need to get right to score 75?
Answer:
31 questions, but it's impossible to score 75%.
Step-by-step explanation:
It's impossible to get exactly a score of 75% out of 42 questions. However, you can get the next closest percentage, which is rounded up to 74% with 31 questions right out of 75.
This is because 31 / 42 = 0.738... You can round 0.738 to 0.74. Then multiply 0.74 by 100, which gives you 74. This means the closest score you can get to 75 is 74% with 31 questions.
You can also score 76% with 32 questions right out of 42 questions. This is because 32 / 42 = 0.761... You can round 0.761 to 0.76. Then multiply 0.76 by 100, which gives you 76.

The expression -310 + 15m represents a submarine that began at a depth of 310 feet below sea level and ascended at a rate of 15 feet per minute. What was the depth of the submarine after 8 minutes?
Answer:
190 feet below sea level
Step-by-step explanation:
d = -310 + 15m
d = -310 + 15(8)
d = -310 + 120
d = -190

The angle corresponding to each other of different triangle are equal.
What are similar triangle ?"Similar triangles are triangles that have the same shape, but their sizes may vary. All equilateral triangles, squares of any side lengths are examples of similar objects. In other words, if two triangles are similar, then their corresponding angles are congruent and corresponding sides are in equal proportion".
Here given,
[tex]\triangle JGR[/tex] is similar to triangle [tex]\triangle MST[/tex]
So, from the definition of similar triangle ,
angle J ≅ angle M
angle G ≅ angle S
angle R ≅ angle T
Hence, option D is correct.

Find the value of x.
Show work. please help
Answer:
x=7
Step-by-step explanation:
Since this is an isosceles triangle the two angles are equal.
3x+6 = 5x-8
Subtract 3x from each side
3x+6-3x = 5x-8-3x
6 = 2x-8
Add 8 to each side
6+8 = 2x-8+8
14 = 2x
Divide each side by 2
14/2 = 2x/2
7 = x
Answer:
x = 7
Step-by-step explanation:
Its two angle is equal so, it is isosceles triangle.
3 x + 6 = 5 x - 8 .. ( in isosceles triangle two side are equal).
3 x + 6 = 5 x - 8
Subtract 3 x from both side
3 x - 3 x + 6 = 5 x - 3 x - 8
6 = 2 x - 8
add 8 to each side
6 + 8 = 2 x - 8 + 8
14 = 2 x
Divide each side by 2
14 / 2 = 2 x / 2
7 = x

Solve for x. 4x-4< 8
AND 9x +5 > 23
is it a, b,c or d ?
Answer:
[tex] A)\displaystyle2 < x < 3[/tex]
Step-by-step explanation:
A compound inequality is an inequality that combines two simple inequalities
we are given that
[tex] \displaystyle 4x - 4 < 8 \ \: \text{and} \: \: 9x + 5 > 23[/tex]
solving x for the first equation:
[tex] \displaystyle 4x - 4 < 8[/tex]
add 4 to both sides:
[tex] \displaystyle 4x < 12[/tex]
divide both sides by 4 and since we are dividing both sides by a positive number the inequality won't swap
[tex] \displaystyle x < 3[/tex]
solving x for the second equation:
[tex] \displaystyle 9x + 5 > 23[/tex]
cancel 5 from both sides:
[tex] \displaystyle 9x > 18[/tex]
divide both sides by 9 and since we are dividing both sides by a positive number:
[tex] \displaystyle x > 2[/tex]
therefore by combining the equations we obtain:
[tex] \displaystyle\boxed{2 < x < 3}[/tex]
hence,
our answer is A)

Find the unknown angle and explain how plzzz
In a straight line, like the one presented before you, there is 180 degrees. So that means 115 degrees + x is gonna equal 180.
So that means, x is gonna be 180 - 115. So x is 65 degrees

Top left Equation: [tex]\frac{2}{3} + (- 2 \frac{1}{3} ) = - 1 \frac{2}{3}[/tex]
Step-by-step explanation:
You start at 2/3, or the left side.
Since the line is directing left, you are subtracting, or adding a negative.
If you see, you are moving 7 - 1/3s to the left
7 x 1/3 = 7 / 3
7 / 3 = 2 1/3
And 2/3 + (-2 1/3) = -1 2/3
