Step-by-step explanation:
Remark
There might be an easier way to do this problem. I'm certain I don't know what it is. Begin by called WY = y
Givens
WY = y
WZ = x
XW = 25 - y
XZ = 24
YZ = 7
Equations
x^2 + y^2 = 7^2
(25 - y)^2 + x^2 = 24^2
Solution
x^2 = 7^2 - y^2
x^2 = 24^2 - (25 - y)^2
Since both xs are the same, you can equate the right side of the equations.
7^2 - y^2 = 24^2 - (25 - y)^2 Expand the brackets
7^2 - y^2 = 24^2 - (625 - 50y + y^2) Remove the brackets.
7^2 - y^2 = 576 - 625 + 50y - y^2 Cancel the y^2. Combine 576 and 625
49 = - 49 + 50y Add 49 to both sides
98 = 50y Divide by 50
y = 1.96
Now use y to find x
x^2 + y^2 = 7^2
x^2 = 7^2 - 1.96^2
x^2 = 45.1584
x = 6.72

Answer:
x = 6.72
Step-by-step explanation:
The triangles are all similar, so the ratios of corresponding sides are the same.
short leg/hypotenuse = 7/25 = x/24
x = 24(7/25)
x = 6.72

The points (-3, -3) and (5, r) lie on a line with slope 3/2
Find the missing coordinate r.
Answers
Answer:
The missing coordinate [tex]r[/tex] is 9.
Step-by-step explanation:
Given the points [tex]P(x,y) = (-3,-3)[/tex] and [tex]Q(x,y) = (5,r)[/tex], the slope of a line passing the two points ([tex]m_{PQ}[/tex]) is determined by equation of secant line:
[tex]m_{PQ} = \frac{y_{Q}-y_{P}}{x_{Q}-x_{P}}[/tex] (1)
[tex]m_{PQ} = \frac{r-(-3)}{5-(-3)}[/tex]
If we know that [tex]m_{PQ} = \frac{3}{2}[/tex], then the value of [tex]r[/tex] is:
[tex]\frac{3}{2} = \frac{r+3}{8}[/tex]
[tex]12 = r + 3[/tex]
[tex]r = 9[/tex]
The missing coordinate [tex]r[/tex] is 9.

∠QSR = 78°∠SQR = 51°Step-by-step explanation:
The measure of an inscribed angle (QTR) is half the measure of the arc it intercepts. The measure of an arc is the same as the measure of the central angle it intercepts. So, we have ...
∠QSR = 2×∠QTR
∠QSR = 2×39°
∠QSR = 78°
__
Sides SQ and SR are radii of circle S, so are the same length. That means triangle QRS is an isosceles triangle and the base angles SQR and SRQ are congruent. The sum of angles in a triangle is 180°, so we have ...
∠QSR + 2(∠SQR) = 180°
78° + 2(∠SQR) = 180° . . . . fill in the value we know
2(∠SQR) = 102° . . . . . . . . . subtract 78°
∠SQR = 51° . . . . . . . . . . . . .divide by 2

Find cosθ, tanθ, and cscθ, where θ is the angle shown in the figure.
Give exact values, not decimal approximations.
Answers
Answer:
Cos(θ) = 7/√58 ; Tan(θ) = 3/7 ; Csc(θ) = √58/3
Step-by-step explanation:
First, let's solve for the hypotenuse by using the Pythagorean Theorem.
a² + b² = c²
⇒ 7² + 3² = c²
⇒ 49 + 9 = c²
⇒ 58 = c²
⇒ √58 = c
Now that we know the hypotenuse is √58, we can solve for the trig ratios.
Cos(θ) = adjacent/hypotenuse = 7/√58
Tan(θ) = opposite/adjacent = 3/7
Csc(θ) = hypotenuse/opposite = √58/3
