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

Evaluate the following expression. log4 256
A. 64
B. 16 C. 4 D. 8
Answers
The simplified value of the expression [tex]log_4[/tex] 256 is 4.
Thus, option (C) is correct.
To evaluate the expression [tex]log_4[/tex] 256, determine the power to which 4 must be raised to obtain 256.
So, the equation can be set up
[tex]4^x[/tex] = 256.
Now, put the value of x one by one as
[tex]4^2 = 16[/tex]
[tex]4^3 = 64[/tex]
[tex]4^4 = 256[/tex]
Thus, when the number 4 raise to the power 4 it gives 256.
Thus, option (C) is correct.

(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?
Answers
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

Zamir needs to determine the height of the building
What’s the Height “A”
What’s Height “B”
What’s the Height of “X”
PLEASE
Answers
Answer:
Height of the building = 115.4 ft.
Step-by-step explanation:
Height of building = AB + 46.4 + CD + 30.5
By applying Pythagoras theorem in ΔABP,
(26)² = (10)²+ (AB)²
676 - 100 = AB²
AB² = 576
AB = 24 ft
By applying sine rule in ΔCDE,
cos(60°) = [tex]\frac{CD}{CE}[/tex]
CD = CE × [tex]\frac{1}{2}[/tex]
CD = [tex]\frac{29}{2}[/tex]
CD = 14.5 ft
Total Height = 24 + 46.4 + 14.5 + 30.5
= 115.4 ft
