.If m∠ ROT = 155, what are m ∠ ROS and m∠TOS?

Can someone explain how to do it also?

ROS is 72 degrees.

TOS is 83 degrees.

Step-by-step explanation:

So we know that the measure of Angle ROT is 155.

Angle ROT is the combined value of Angle ROS and Angle TOS. In other words:

Substitute 155 for ROT, (4x-20) for ROS, and (3x+14) for TOS. Thus:

Combine like terms:

Add:

Add 6 to both sides:

Divide both sides by 7:

So, the value of x is 23.

Now, plug that into each of the Angle equations to solve for each angle:

Multiply:

Subtract:

Same thing for TOS:

Multiply:

Add:

And we're done!

question is incomplete.

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
