Answer:

8.4 cm

Step-by-step explanation:

The sides involved are opposite and adjacent to the given angle. Therefore, you should use the tangent ratio.

Substitute:

tanx = opp/adj

tan35 = x/12

Multiply by 12 on both sides:

12(tan35) = (x/12)12

12(tan35) = x

Solve:

12(tan35) = x

8.4 = x

aalyn [17]

Answer:

The reporter surveyed 60 girls.

Step-by-step explanation:

From the information given, you can use a rule of three to find the amount of girls that the reporter surveyed which is 100% given that 39 girls represent 65%:

65% → 39

100% → x

x=(100*39)/65

x=60

According to this, the answer is that the reporter surveyed 60 girls.

A line has the equation x = -8 What is the equation of the line parallel to this line and going through the point, ( -3, -1 )?

Talja [164]

X=-8 is just a vertical line 8 units to the left of the origin.

So a parallel line will also be vertical and as asked it must pass through (-3,-1) so it is:

x=-3

I need to know this question for edge

Rus_ich [418]

Answer:

first function:

$f(x) = \dfrac{2 - 10}{2 - 0} x + 10 = \\ - 4x + 10$

second one:

$g(x) = \cfrac{ - 4 - 2}{2 - 0} x + 2 = \\ - 3x + 2$

now the intersection:

-4x+10=-3x+2

x=8

then y

y = -4×8+10 = -22

so it's

(8,-22)
