A triangle with Side lengths a units, b units, and c units is shown.
WHICH EQUATION IS TRUE FOR THE TRIANGLE?
A- Sin (55°)=a/c
B- Cos(55°)=c/b
C- Cos(55°)=a/b
D- Tan(55°)=c/a
Will give brainliest!
Answers
Option A is the correct answer because the ratio between the opposite side and the hypotenuse side is correct.
Triangle :
A right-angled triangle is a triangle, that has one of its interior angles equal to 90 degrees or any one angle is a right angle. Therefore, this triangle is also called the right triangle or 90-degree triangle. The right triangle plays an important role in trigonometry. Let us learn more about this triangle in this article.
A triangle with Side lengths a unit, b units, and c units.
"Opposite" is opposite to the angle θ
"Adjacent" is adjacent (next to) to the angle θ
"Hypotenuse" is the long one
A)
Sin 55 = a/c
Sin θ = opposite / hypotenuse
Option A ) is correct Sin 55 = a/c
B)
Cos(55°)=c/b
Cos θ = Adjacent / hypotenuse
Cos 55 = c/ b is not equal to the Adjacent / hypotenuse
Option B) is not a correct answer because the ratio is between Adjacent and Hypotenuse.
C)
Cos(55°)=a/b
Cos θ = Adjacent / hypotenuse
Cos 55 = a/ b is not equal to the Adjacent / hypotenuse
Option C) is not a correct answer because the ratio is between Adjacent and Hypotenuse.
D)
Tan(55°)=c/a
Tan θ = Opposite / Adjacent
Tan 55 = c/a is not equal to the Opposite / Adjacent
Option D) is not a correct answer because the ratio is between Opposite and Adjacent.

Answer:
150 boys
Step-by-step explanation:
equation:
⇒ 5x + 4x = 270
add like terms:
⇒ 9x = 270
divide 9 on both sides:
⇒ [tex]\frac{9x}{9} = \frac{270}{9}[/tex]
solve:
⇒ x = 30
take original equation and subtitute 30 for x;
⇒5 x 30 + 4 x 30 = 270
⇒ 150 + 120 = 270
We can see that if there were 270 students, 150 would be boys and 120 would be girls.

On Saturday, Lucas drove 4x – 5 miles. On Sunday, he drove 3x – 10 miles. What is the difference in miles driven? write an expression and simplify it.
Answers
________________________________
Here, Distance covered by Lucas on Saturday
= 4x – 5 miles
Now, Distance covered by Lucas on Sunday
= 3x – 10 miles
________________________________
Hence, Difference between the distances
would be / –
Distance covered on Saturday – Distance covered on Sunday
= (4x – 5) – (3x – 10)
= 4x – 5 – 3x + 10
[ Because (– * + = – ) And ( – * – = +) ]
= 4x – 3x + 10 – 5
= 1x – 5
= x – 5 ( – Ans )
Hence, The difference between Distance covered ( In miles ) is ( x – 5 ) .

PLEASE HELP MY OUT Solve: -2X + 5 +4X + 9 = 3 (6 + 4X) -12X
Show your work
Answers
Answer:
x=2
Step-by-step explanation:
first we will distribute out everything
-2x +5 +4x+ 9 = 3(6 +4x)- 12x
(multiply 3 to both 6 and 4x)
-2x +5 +4x+ 9= 18 +12x -12x
then combine like variables on both sides
(add -2x and 4x and add 5 and 9, for the other side add 12x and -12x)
2x+14= 18
then isolate x
2x=4
x=2
and substitute x for 2 to double check
-2(2)+5+4(2)+9=3(6+4(2))-12(2)
18=18
therefore 2 is correct
Brian rolls a fair dice 12 times. How many times would Brian expect to roll a number greater than 4?
Answers
Brian is expected to roll a number greater than 4, 4 times
How to determine the expected row?In a fair die, we have:
Faces = 6
Faces greater than 4 = 2 i.e. 5 and 6
So, the probability to roll a number greater than 4 is:
p = 2/6
When the dice is rolled 12 times, the expected value is:
Expected = 2/6 * 12
Evaluate
Expected = 4
Hence, Brian is expected to roll a number greater than 4, 4 times

The center of the circle is point: C=(1,5).
The radius of the circle is r=3.
Step-by-step explanation:
x² + y² -2x - 10y + 17 = 0
Find the center and radius of this circle
We have the equation
x² + y² -2x - 10y + 17 = 0
We collect like terms
x² - 2x + y² - 10y = -17
x² - 2x + (-2/2)² + y² - 10y + (-10/2)² = -17 + (-2/2)² + (-10/2)²
The center of the circle is point: C=(1,5).
The radius of the circle is r=3.

Q3. In a hydraulic lift, a 1400 N force is applied to a 0.5 m2 piston. Calculate the minimum surface area of the large piston to lift 5000 N.
Answers
Answer:
1.8m^2 approx
Step-by-step explanation:
Given data
P1= 1400N
A1=0.5m^2
P2=5000 N
A2=??
Let us apply the formula to calculate the Area A2
P1/A1= P2/A2
substitute
1400/0.5= 5000/A2
cross multiply
1400*A2= 5000*0.5
1400*A2= 2500
A2= 2500/1400
A2= 1.78
Hence the Area is 1.8m^2 approx

Step-by-step explanation:
Before starting this question, you need to know that the total degree of any given triangle is 180 degrees.
Now looking at the question, we know one side is 90 degree since it is a right triangle.
180-90=90
This let us know that the remaining two angles will have to add up to equal to 90 degrees.
2x+1+5x+5=90
First, combine like terms.
7x+6=90
Now we have to get x by itself, subtract 6 on both sides then divide by 7.
7x=84
x=12
