Answer:
<h2>137°</h2>
Step-by-step explanation:
The pentagon RSTYZ is a regular polygon. Therefore all angles are congruent.
If m∠RST = 108°, then m∠STY = 108°.
We have the equation:
m∠UTY + m∠STY + m∠STU = 360°.
Substitute m∠STY = 108° and m∠UTY = 115°.
115° + 108° + m∠STU = 360°
223° + m∠STU = 360° <em>subtract 223° from both sides</em>
m∠STU = 137°
I really don’t know the answer I’m sorry
Given:
$2.50 off any electronic book for an online bookstore.
let p = original price in dollars
d = discounted price in dollars
p = d + $2.50
The equation above is the working equation to determine the original and discounted price of any ebook purchased by Jason. <span />
First, ask yourself: What is a polynomial? It's an algebraic expression in which all powers of x are zero or positive integers.
Eliminate E because -2 is not a positive integer exponent.
Accept D because all of the powers of x are positive integers: {3, 2, 1, 0}
Eliminate C because -3 is not a positive integer power
Eliminate A and B because of the fractional or negative exponents shown.
Only D is a polynomial.
