Put all the angles = 180 (for a triangle's sum is 180 degrees)

x - 4 + 100 + 3x = 180

Add numbers (& common variables) together

3x + x + 100 - 4 = 180

4x + 96 = 180

isolate the x, subtract 96 from both sides

4x + 96 (-96) = 180 (-96)

4x = 180 - 96

4x = 84

isolate the x, divide 4 from both sides

4x = 84

4x/4 = 84/4

x = 84/4

x = 21°

Emily measured the height of a dresser as 4.27 feet, but the actual height was 4 feet. What is the percentage of error in Emily’
Assoli18 [71]
We need to find the percentage of the extra feet that she measured, so first we have to find out how much that is. We can do this by simply subtracting:

4.27 - 4 = 0.27

Now we can set up a proportion to find the percentage.

\frac{0.27}{4}  \frac{x}{100}

Solve for x

0.27 x 100 = 27
27/4 = 6.75

The answer is 6.75% :)

Hopefully this helps! If you have any more questions or don't understand, feel free to DM me, and I'll get back to you ASAP! :)
