Step-by-step explanation:
1) the rule: m∠1+m∠2+m∠3=180°;
2) according to the rule above: m∠P+m∠Q+m∠R=180°;
x+x+43+2x-15=180°; ⇔ 4x=152°; ⇒ <u>x=38°</u>;
3) the angles: P=2x-15=<u>61°;</u> Q=x+43=<u>81°</u>; R=x=<u>38°</u>.
Area = 7*7 + 1/2 * 7 * 3 = 49 + 10.5 = 59.5 cm^2

The amount of Tina money can be expressed in an exponent function like this:
an= $1100(1.0725)^n
The variable an represent the total money and variable n is the years needed to achieve that amount.
Then, the time needed for the money to reach $6,600 would be:
an= $1100(1.0725)^n
$6,600= $1100(1.0725)^n
$1,100(6)= $1100(1.0725)^n
6= (1.0725)^n
n= log1.075 6
n= 24.78
Answer:
Your answer will be 1,330 I hope this helps
