Question

Question is find the value of R
there is no r=,just the number


I am so confused and this is due at 11:59 please help me!!

Answer 1

Answer:

r = 5°, remove the r if you want to

Step-by-step explanation:

Exterior angles theorem:

The exterior angle equals the sum of the two remote interior angles

In this case, 119° = 90° + 5r + 4°

Let's solve it :

119° = 90° + 5r° + 4°

Subtract 94 from both sides

25° = 5r°

Divide both sides by 5

r = 5°

If my answer is incorrect, pls correct me!

Answer 2

How I was taught, maybe it will help you:

The number after the equal sign would be 90, because it is a right triangle:

5r+4=90

Subtract 4 from both sides of the equation, so the 4's cancel and equal 0. Then you have to subtract 4 from 90. So 90-4 is 86.

Now, you should be left with:

5r=90

Now what you do is divide 5 from both sides of the equation, since 5r is like saying 5*r or 5(r).

Now, you should have this:

r=90/5

90/5 is 18.

Your answer should be r=18.

Hope I could help! :D
