We know that,

[tex]\sf\pink{Sum\:of\:angles\:of\:a\:triangle\:=\:180°}[/tex]

➪ ∠ ABC + ∠ BAC + ∠ BCA = 180°

➪ 81° + a° + 62° = 180°

➪ a° + 143° = 180°

➪ a° = 180° - 143°

➪ a° = 37°

Therefore, the measure of a is 37°.

Now, the three angles of the triangle are 81°, 37° and 62°.

Answer:

(B) Parallel to x-axis

Step-by-step explanation:

y = 7

This is a constant line, in which the value of y is always of 7, no matter the value of x.

In a line in which the value of y is constant, this line is parallel to the x-axis, so the correct answer to this question is given by option b.

Answer:

x = 2 2/3

Step-by-step explanation:

6(x - 2) = 4

Distribute

6x - 12 = 4

Add 12 to each side

6x-12+12 = 4+12

6x = 16

Divide by 6

6x/6 = 16/6

x = 8/3

x = 2 2/3

Answer:128.74

Step-by-step explanation:

The midpoint for any segment/line when you're given the start and end point of the line as A=(x1,y1) and B=(x2,y2) is

(   ((x1 + x2) /2), ((y1 + y2)/2)   )

So here the point is

(  (-2+6)/2), (-6+12)/2)  )

= (2, 3)

So it's the second option

Answer:

[tex]x = \sqrt{72[/tex]

Step-by-step explanation:

Given

Number x [tex]equals[/tex] square root of [tex]72[/tex]

Required

Rewrite using mathematical symbols

equals is represented as: =

So, we have:

Number x [tex]=[/tex] square root of [tex]72[/tex]

Number x can be written as just "x". So, we have:

x [tex]=[/tex] square root of [tex]72[/tex]

square root  is represented as: [tex]\sqrt[/tex]. So, we have:

[tex]x = \sqrt{72[/tex]

Circumference Formula: 2πr or dπ ⇒ r=radius and d=diamater

1.) π≈3.14

2.) 24×3.14=75.36

Answer: [tex]\dfrac{15}{64}[/tex]

Step-by-step explanation:

Given

Inside radius of figure [tex]r_1=\frac{14}{2}=7\ ft[/tex]

Outside radius of figure [tex]r_2=\frac{16}{2}=8\ ft[/tex]

Area of outside region is [tex]A_1=\pi (8^2)[/tex]

Area of inside region [tex]A_2=\pi (7)^2[/tex]

Area of shaded region [tex]A_1-A_2[/tex]

Probability that point lies inside the shaded region is

[tex]\Rightarrow P=\dfrac{A_1-A_2}{A_1}\\\\\Rightarrow P=\dfrac{\pi (8^2-7^2)}{\pi 8^2}\\\\\Rightarrow P=\dfrac{64-49}{64}\\\\\Rightarrow P=\dfrac{15}{64}[/tex]

Answer:

Find length opposite to 30deg

Opposite = tan(30)*42

= 24.2

Whole side = 24.2+10

Find angle of 0 + 30deg: (say x)

Tan(x) = 33.2/42

Arctan(0.79) = x

x = 38.3

The angle to find:

38.3-30:

8.3

The angle is 8.3deg.

Answer:

18

Step-by-step explanation:

First, we know that the total is equal to 100%. We then know that 14 students make up 43.75%, and eight grade students make up the rest, at 100-43.75=56.25%.

One way we can figure this out to find how many students make up each percent. To find this, we can simply divide the number of students (14) by their percent (43.75) to get 14 students/43.75 percent = 0.32 students per percent. We can then multiply this by 56.25 to get 18 as our answer for the number of eight graders.

Answer: 18

Step-by-step explanation:

14/43.75% = 0.32

56.25 × 0.32 = 18

Therefore, 18 is the answer to this equation.
