<h3>What is an
equation?</h3>
An equation is an expression used to show the relationship between two or more numbers and variables.
From the diagram:
1) x + 146° = 180° (sum of angles in a straight line)
x = 34°
2) x + 62.9° = 90° (complementary angles)
x = 17.1°
3) x + 105° = 180° (sum of angles in a straight line)
x = 75°
The value of x in each figure is 34°, 17.1° and 75° respectively.

Answer:
She typed 32 words in her letter
Step-by-step explanation:
Assume that the letter has x words
∵ She typed x words in her letter
∵ She misspelled 8 words
∵ She misspelled 25% of the words she typed
∴ She misspelled 25% of x
→ That means 8 is equivalent to 25% of x
∴ 25% of x = 8
∴ 25% × x = 8
→ Change 25% to decimal by divide it by 100
∵ 25% = 25 ÷ 100 = 0.25
∴ 0.25 × x = 8
∴ 0.25x = 8
→ Divide both sides by 0.25
∵
= ![\frac{8}{0.25}](https://tex.z-dn.net/?f=%5Cfrac%7B8%7D%7B0.25%7D)
∴ x = 32
∵ x represents the number of words that she typed in the letter
∴ She typed 32 words in her letter
