Given right triangle GYK, what is the value of tan(G)?

Svetradugi [14.3K]

Answer:

OPTION D (√3)

Step-by-step explanation:

By definition, the tangent of a right triangle is:

$tan\alpha=opposite/adjacent$

Then, you have the right triangle GYK, you can find the tan(G) as you can see below:

Find KY as following:

$tan(30)=27/KY=\\KY=27/tan(30)\\KY=27\sqrt{3}$

Then, you have:

$tan(G)=27\sqrt{3}/27$

When you simplify, you obtain:

$tan(G)=\sqrt{3}$

If three points (5,1) , (1,-1) and (m,4) are collinear.Find m

krek1111 [17]

Answer:

m = 11

Step-by-step explanation:

Since the points are collinear then the slope between points are equal.

Calculate the slope m using the slope formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (5, 1) and (x₂, y₂ ) = (1, - 1)

m = $\frac{-1-1}{1-5}$ = $\frac{-2}{-4}$ = $\frac{1}{2}$

Repeat with

(x₁, y₁ ) = (1, - 1) and (x₂, y₂ ) = (m, 4)

m = $\frac{4+1}{m-1}$ = $\frac{5}{m-1}$ = $\frac{1}{2}$

Cross- multiply

m - 1 = 10 ( add 1 to both sides )

m = 11

The function V= √1.223w expresses the landing speed, V (in feet per second), as a function of gross weight, w (in pounds), of an

mylen [45]

<span>an equation that expresses the gross weight of an aircraft as a function of its landing speed will be given as follows:
</span><span> V= √1.223w
we make w the subject of the equation, we start by dividing both squaring both sides:
</span>V²=(√1.223w)²
V²=1.223w
next we divide both sides by 1.223 to get :
V²/1.223=1.223w/1.223
w=V²/1.223
hence the answer will be w=V²/1.223

In the figure shown, r || s. If the measure of ∠ 2 = 146°, what is the measure of ∠ 7

borishaifa [10]

Answer:

34°

Step-by-step explanation:

1. First, let's find the measure of ∠1 because since r || s, that means ∠1 = ∠7 because they're both alternate exterior angles. Alternate exterior angles are congruent.

2. (Solving for ∠1)

$146 + x = 180$
$146 + x - 146 = 180 - 146$
$x = 34$

3. Now, since we know ∠1 = ∠7, ∠7 = 34°.
