Plz help I may mark Brainiest
Answer:
A. 6
Step-by-step explanation:
[tex]10x \degree + 30 \degree = 90 \degree \\(complementary \:angles) \\\\ 10x \degree = 90 \degree - 30 \degree\\ \\ 10x \degree = 60 \degree \\ \\ 10x = 60 \\ \\ x = \frac{60}{10} \\ \\ x = 6[/tex]

How to find the slope for (2,2) and (-1,2)
Answer:
Slope = 0
slope is the same as gradient, so you will use the formula
M = y2 - y1 / x2 - x1 in this case (2,2) and (-1.2)
the first 2,is x1.then the other 2 in the first coordinate is y1 , for the last coordinate -1 is x2 and 2 is y2, use the formula I gave you , you will see that the answer is 0
The value of tan60° is ______ . * 1 point 1/√3 0 1 √3
Answer:
Therefore, the exact value of Tan 60 degrees is √3. We can also derive the values of tan 0°, 30°, 45°, 90°, 180°, 270° and 360° in the same way
The value of tan 60° is √3, approximately 1.732.
To calculate the value of tan 60°, we need to use the trigonometric function tangent. Tan 60° represents the ratio of the length of the side opposite the angle to the length of the adjacent side in a right triangle with a 60° angle.
In a 30°-60°-90° right triangle, the length of the opposite side opposite the 60° angle is equal to the square root of 3 times the length of the adjacent side.
The length of the opposite side is √3, and the length of the adjacent side is 1.
Using these values, we can calculate the value of tan 60°:
tan 60° = (opposite side) / (adjacent side) = (√3) / 1 = √3.
Therefore, the value of tan 60° is √3, approximately 1.732.

A quadratic function is represented by the graph. (graph below.) (do a-d.)
(a) What is the equation of the axis of symmetry of the function?
(b) What are the coordinates of the vertex of the function?
(c) What are the coordinates of the x-intercepts of the function?
(d) What are the coordinates of the y-intercept of the function?
Answer:
The axis of symmetry is x=1
The vertex is (1,-9)
The x-intercepts are (4,0) and (-2,0)
The y-intercept is (0,-8)
Step-by-step explanation:
axis of symmetry is the line where the vertex is, so in the quadratic of x^2, the axis of symmetry would be zero because half of the equation is on one side and the other half on the other side
The vertex is the lowest point on the quadratic, on the y values
the x-intercepts are the places the graph intercepts the x-axis.
The y-intercepts are the places the graph intercepts the y-axis

Answer:
x = 50°
Step-by-step explanation:
the sum of the exterior angles of any polygon is 360°
2x-12 + 32 + 2x + x + 90 = 360
5x + 110 = 360
5x = 250
x = 50

Answer:
1st pic:
x = 61
left angle = 125 degrees
right angle = 55 degrees
2nd pic:
n = 14
left angle = 78 degrees
right angle = 102 degrees
Step-by-step explanation:
1st pic:
use the following equation ⇒ 2x + 3 + x - 6 = 180
combine like terms ⇒ 3x - 3 = 180
add 6 on both sides ⇒ 3x - 3 + 3 = 180 + 3 ⇒ 3x = 183
divide both sides by 3 ⇒ [tex]\frac{3x}{3} = \frac{183}{3}[/tex]
x = 61
solve the angles by subtituting 61 for x
left angle = 2x + 3 ⇒ 2 x 61 + 3 ⇒ 125 degrees
right angle = x - 6 ⇒ 61 - 6 ⇒ 55 degrees
2nd pic:
use the following equation ⇒ 4n + 22 + 8n - 10 = 180
combine like terms ⇒ 12n + 12= 180
subtract 12 on both sides ⇒ 12n + 12 - 12 = 180 - 12 ⇒ 12n = 168
divide both sides by 12 ⇒ [tex]\frac{12n}{12} = \frac{168}{12}[/tex]
n = 14
you can find the angles by substituting 14 for n:
left angle = 4n + 22 ⇒ 4 x 14 + 22 =78 degrees
right angle: 8n - 10 ⇒ 8 x 14 - 10 = 102 degrees
