The pair of equations below is a result of constructing the altitude, h, in Triangle ABC is A; sin C = h/a and sin A = h/c.
What are trigonometric identities?Trigonometric identities are the functions that include trigonometric functions such as sine, cosine, tangents, secant, and, cot.
We know:
[tex]\sin(\theta) = \dfrac{\text{Length of perpendicular}}{\text{Length of Hypotenuse}}[/tex]
So from the attached figure;
sin C = h/a
sin A = h/c
These expressions have an h term in common. We can combine them if we can find forms of the expressions in terms;
h = a (sin C)
h = c (sin A)
Thus, option A is correct pair.

35 percent of the students are boys which is 259 find the total number of the students and girls
Answers
Answer:
740 total students, 481 total girls
Step-by-step explanation:
Let x be the total number of students and y be the total number of girls
x -
You know that 35% of the students is 259 students. If you convert this into algebra, you can write : 0.35x = 259, after simplifying, you know that x = 740.
y-
You know that 35% of the students are boys, so 65% must be girls. You can say that 65% of x is y and write the equation 0.65(740)=y. After simplifying, you can see that y = 481.

Let's solve your equation step-by-step.
4x + x + 5 − 9 + x = −3 − 7 + x
Step 1: Simplify both sides of the equation.
4x + x + 5 − 9 + x = −3 − 7 + x
4x + x + 5 + −9 + x = −3 + −7 + x
( 4x + x + x ) + ( 5 + −9 ) = ( x ) + ( −3 + −7 )
( Combine Like Terms )
6x + −4 = x + −10
6x − 4 = x − 10
Step 2: Subtract x from both sides.
6x − 4 − x = x − 10 − x
5x − 4 = −10
Step 3: Add 4 to both sides.
5x − 4 + 4 = −10 + 4
5x = −6
Step 4: Divide both sides by 5.
5x / 5 = −6 / 5
x= −6 / 5
Answer:
x= −6 / 5

How do you graph a quadratic function?
Answers
Answer:
Step-by-step explanation:
Compare the equation with the standard form, y=ax2+bx+c . Since the value of a is positive, the parabola opens up.
So, y=0 implies, by the zero product property, x+4=0 or x−2=0 .
Substitute x=−1 in the equation y=−x2−2x+8 to find the y -coordinate of the vertex.

45 inch board cut into three pieces so that the second piece is 3 times as long as the first piece and the third piece is 5 times as long as the first piece . find the lengths of all three pieces
Answers
Answer:65
Step-by-step explanation:
Length of first, second and third piece are 5, 15 ,25 inch
Given that;
Length of board = 45 inch
Second cut is 3 times as long as the first piece
Third cut is 5 times as long as the first piece
Find:
Length of all three piece
Computation:
Assume;
Length of first piece = a
So,
Length of second piece = 3a
Length of third piece = 5a
So,
Length of first piece + Length of second piece + Length of third piece = Total length
a + 3a + 5a = 45
9a = 45
a = 5
So,
Length of first piece = a
Length of first piece = 5 inch
Length of second piece = 3a = 3(5)
Length of second piece = 15 inch
Length of third piece = 5a = 5(5)
Length of third piece = 25 inch

[tex]\frac{1}{9} + 9[/tex]
whole numbers always go over a 1

Answer:
Step-by-step explanation:
Sin(x) = opposite / hypotenuse.
opposite = 28 The opposite is not connected to the angle.
hypotenuse= 35
Sin(x) = 28/35 = 4/5
Cos(x) = adjacent / hypotenuse.
The adjacent side is part of the angle
adjacent = 21
hypotenuse = 35
Cos(x) = 21 / 35 = 3/5
Tan(x) = opposite / adjacent
opposite = 28
adjacent = 21
Tan(x) = 28/21
Tan(x) = 4/3
