I need to finish this usa test prep now plz help
Slav-nsk [51]

Answer:

R = 101

S = 131

Step-by-step explanation:

First, you will want to get your angle T. Since T is on the same line as the angle with 128 degree, you can easily find angel T. They are supplementary angels and form 180.

T=180-128

T=52

You also know that all angles in a triangle equal to 180

Use that to find angle S

180 = R+S+T

180 = 79 + S + 52

180 - 79 - 52 = S

49 = S, exterior S = 180-49 = 131

Exterior R = 180 - 79 = 101

Now add all your exteriors

Two students are reading a novel. Ashley reads 10 pages per day. Carly reads 8 pages per day, but she starts
natulia [17]

Answer:

On day 20, they should both be on page 200

Step-by-step explanation:

I set the 2 equations up:

10d=8d+40 and then subtracted 8d from both sides

2d=40 and then divided both sides by 2

d=20

I then took 20 and multiplied it by 10 for Ashley (200) and then multiplied it by 8 for Carly (160) and added 40 (200)

Hope this helps!

What are the solutions to the equation x2 = 289?
artcher [175]
Because this is a second degree equation you will have 2 solutions.  When you take the square root of a number you have to account for both the positive and negative roots.  Since the square root of 289 is 17 then your solutions are +17 and -17.
