Answer:

45°

Step-by-step explanation:

three angles in a triangle sum up to 180

90° + a + a = 180°

90° + 2a = 180°

2a = 180°-90°

2a = 90°

a = 45°

The cost to a store for a box of cereal is $2.50. The store is selling the box of cereal for $3.50. What is the percent of marku

zysi [14]

Well, the cereal cost 2.5, and the store is selling for 3.5, so is 1 buck more.

if we take 2.5 to be the 100%, what is 1 off of it in percentage?

$\bf \begin{array}{ccll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
2.5&100\\
1&p
\end{array}\implies \cfrac{2.5}{1}=\cfrac{100}{p}\implies p=\cfrac{1\cdot 100}{2.5}\implies p=\stackrel{\%}{40}$
