Answer:

x = 23

Step-by-step explanation:

Seeing same-side exterior angles theoreom,

both of these angles add up to 180°.

Looking at this,

3x + (4x+19) = 180

3x + 4x + 19 = 180

Subtracting both sides by 19 to get x on the LHS:

3x + 4x + 19 - 19 = 180 - 19

7x = 161

x = 23

Find the length of ac

maksim [4K]

Answer:

$\boxed{AC = 42.99}$

Step-by-step explanation:

Tan 34 = $\frac{opposite}{adjacent}$

Where opposite = 29, adjacent = AC

So,

0.674 = $\frac{29}{AC}$

AC = $\frac{29}{0.674}$

AC = 42.99

The graph shows a proportional relationship.What is the unit rate? Enter your answer as an improper fraction in simplest form in

ruslelena [56]

That is the slope
rise/run
we see we have (2/5,1/2)
rise is y, run is x
(x,y)
((1/2)/(2/5)=(1/2)(2/5)=2/10=1/5

unit rate is y=(1/5)x
