Answer:
0° and 18°
Step-by-step explanation:
3tan²β - tanβ = 0
tanβ(3tanβ - 1) = 0
tan β = 0 ⇒ [tex]\beta _{1}[/tex] = 0°
3tan β - 1 = 0 ⇒ tan β = [tex]\frac{1}{3}[/tex] ⇒ [tex]\beta _{2}[/tex] = arctan ( [tex]\frac{1}{3}[/tex] ) ≈ 18°
Answer:
[tex]3 \tan {}^{2} \theta - \tan\theta= 0 \\ \tan\theta(3 \tan \theta- 1) = 0✓\\\\\tan\theta = 0 \\\boxed{\theta = 0°} ✓\\\\ 3 \tan\theta - 1 = 0 \\3 \tan \theta = 1 \\ \tan \theta = \frac{1}{3} \\ \theta = { \tan }^{ - 1} ( \frac{1}{3} ) \\\boxed{\theta = 18.4°}✓[/tex]
★ Value of the ∅ is 0° and 18.4°.Related Questions

Thus, the set of side measures 7, 8, 15 does not form a Pythagorean Triplet, and thus not a right triangle.

The length of the rectangle shown below is represented by the expression (x - 2)2. The width is represented by the expression (3x - 5). What is the area of the rectangle?
Answers
Answer:
(6x² - 22x + 20) square units
Step-by-step explanation:
The area of a rectangle is calculated as:
Length × Width
From the question
Length = (x - 2)2 = 2x - 4
Widths = 3x - 5
The area of the rectangle =
(2x - 4 ) × (3x - 5)
2x(3x - 5) -4(3x - 5)
6x² - 10x - 12x + 20
6x² - 22x + 20
The area of the rectangle =
(6x² - 22x + 20) square units

Write an equation in slope-intercept form of the line going through the points (-1,6)
and (5, 0).
Answers
Answer:
Equation in slope-intercept form : y = -1x + 5
Step-by-step explanation:
Given points are:
(-1, 6) and (5,0)
We will first find the slope.
[tex]m = \frac{y_2-y_1}{x_2-x_1}\\\\m = \frac{0-6}{5-(-1)}\\\\m = \frac{-6}{6}\\m = -1[/tex]
The general equation for slope intercept form is;
y = mx + b
Now we will find the value of b by putting one of the points in the general equation
Putting (5,0)
0 = -1(5) + b
0 = -5 + b
b = 5
The equation in slope intercept form is;
y = -1x + 5
Hence,
Equation in slope-intercept form : y = -1x + 5
Move points A and B to different locations on the coordinate plane to change the length and slope of . (Pick a slope that is not purely horizontal or vertical.) Next, choose a ratio other than 2 : 3, and divide using the selected ratio. Repeat the steps from questions 1 through 4 for the new line segment and ratio. Show your work. When you are finished, take a screenshot with the distances displayed on the divided line segment and paste it below your work.
Urgent!!! PLEASE HELP!!!
Answers
Answer:
hope this displays, sorry if it doesn't
Step-by-step explanation:
If we take (1,2) and (2,4) then the slope will be 2. and is we change it to (3,5) and (8,8) then slope will be 3/5.
What is slope?The slope is the vertical distance which is calculated by ratio of difference between y coordinates and x coordinates.
How to find slope?The formula of slope is (y2-y1)/(x2-x1).
Points A and B are (1,2) and (2,4) then slope=4-2/2-1=2
Length of line will be [tex]\sqrt{(4-2)^{2} +(2-1)^{2} }[/tex]
=[tex]\sqrt{4+1}[/tex]
=[tex]\sqrt{5} units[/tex]
Change the points to (3,5) and (8,8) slope becomes=8-5/8-3=3/5
length of line will be [tex]\sqrt{(8-5)^{2} +(8-3)^{2} }[/tex]
=[tex]\sqrt{9+25}[/tex]
=[tex]\sqrt{34}[/tex] units.
let the ratio be 2:9
If we select this and divide using 2:9 then it will become 2:9.
