Answer:

Step-by-step explanation:

You can use division because the angles are the same:

From the first one to the second you divide by 2

16/2=8

So that means x/2=11

So x=22

What does pq equal and how do I find it???

Kay [80]

Use trigonometry.

sinQ = 14/50 = 0.28
-> angle Q = sin^-1(0.28) = approx 16 degrees

-> cosQ = A/H -> cos16 = PQ/50

=> PQ = 50*cos16 = approx 48.06

So yea.

The slope of the line whose equation is 5 x - 3 y = 4 is <br> 5/3 <br> 4/5 <br> -3/5

vlada-n [284]

The slope-intercept form: y = mx + b

m - slope

b - y-intercept

We have:

$5x-3y=4\qquad|\text{subtract 5x from both sides}\\\\-3y=-5x+4\qquad|\text{divide both sides by (-3)}\\\\y=\dfrac{5}{3}x-\dfrac{4}{3}$
