I need help... I honestly don’t know.
Serhud [2]

Answer:

∡ABC=55°

Step-by-step explanation:

<u>Step 1: Identify all angles</u>

∠A=(x+45)°

∠B=(6x+5)°

∠C=(3x)°

∠ABC=(180-∠B)°=(180-(6x+5))°

<u>Step 2: Use the Triangle Angle Sum Theorem</u>

∠A+∠ABC+∠C=180°

(x+45)+(180-(6x+5))+(3x)=180

x+45+180-6x-5+3x=180

-2x+45+180-5=180

-2x+45-5=0

-2x+40=0

-2x=-40

x=20

<u>Step 3: Plug in x=20 for ∠ABC</u>

∠ABC=(180-(6x+5))°

(180-6(20)-5)°

(180-120-5)°

(60-5)°

55°

So ∡ABC=55°

Jean drove 64 miles per hour for a total of 448 miles on a trip. She used the equation below to calculate the time, t, it would
Alexandra [31]

Answer:

Step-by-step explanation:

since there is no given formula I'm guessing that's what we want to find?

use the dist. = rate * time   formula for this kind of problem

or  d = r*t     ( this looks like the word  "dirt" to me so I call this the dirt formula partly b/c it's dirt simple, and it's generally about moving across some give dist. of dirt  :P )  

so Jean's rate is 64 MPH

her total distance is 448 miles  

rearrange the  d = rt  formula so that you are solving for the thing you don't know.. yet....   t (time)  for this case

soooo...

d/r = t

plug in number

448 / 64 = t

7 = t  (in hours)
