The angles are 27°, 27° and 126°
let the 2 equal angles be x then the third angle = 3x + 45
sum of 3 angles = x + x + 3x + 45 = 5x + 45 = 180
hence 5x = 180 - 45 = 135⇒ x= 135/5 = 27
the angles are 27°, 27° and 3x + 45 =81 + 45 = 126°
<h3>Interest rate required for Antonio’s investment to double in value in 12 years is 8.3 % per annum</h3>
<em><u>Solution:</u></em>
Given that,
Antonio wants to invest $7600 in a saving account
Antonio’s investment to double in value in 12 years
To find: Rate of interest
<em><u>The total amount using simple interest is given as:</u></em>

Where,
p is the principal
r is the rate of interest
t is the number of years
From given,
p = 7600
t = 12 years
r = ?
Antonio’s investment to double
Therefore,
A = 2(7600) = 15200
<em><u>Substituting the values we get,</u></em>


Thus interest rate required for Antonio’s investment to double in value in 12 years is 8.3 % per annum
You could make a small (easily repaired) leak and watch it for the amount of time you need to conclude what you need to.
2 + 3 is 5
4 + 1 is 5
so they are equal. what sign is that?
Answer:
Option 4 - 
Step-by-step explanation:
To find : Which set of rational numbers is arranged from least to greatest?
Solution :
The set of rational numbers are

Writing all number in one form,


Now, -1.4<-0.5<0.2<3
From least to greatest the set of natural numbers are

So, 
Therefore, option 4 is correct.
