So 2.5^2= 1.5^2 +b^2
6.25= 2.25 +b^2
Subtract 2.25 on each side
4= b^2
Take the square root of each side
X=2
Hope it helps

The fraction 2/5 added by 3/4 will be 1 3/20.
<h3>How to calculate the fraction?</h3>
A fraction is simply a piece of a whole. The number is represented mathematically as a quotient where the numerator and denominator are split. In a simple fraction, the numerator as well as the denominator are both integers. On the other hand, a fraction appears in the numerator or the denominator of a complex fraction.
The fraction will be illustrated thus:
=✓2/5 + 3/4
= 8/20 + 15/20
= 23/20
= 1 3/20
The value is 1 3/20.

The two plans charge the same amount in 11 months.
The plan I would recommend if the plans are contracted for two months is the Fidoll plan.
<h3> When will the two plans charge the same amount?</h3>
The equation that represents the amount that would be paid by Kayla if she buys the phone from Rongers is : $127x
Where x represents the number of months
The equation that represents the amount that would be paid by Kayla if she buys the phone from Fidoll is : $363 + $94x
Where x represents the number of months
The two above equations would be equal when the plan charge the same amount: $363 + $94x = $127x
Combine similar terms
$363 = $127x - $94x
Add similar terms
$363 = $33x
Divide both sides by 33
x = 11 months
<h3>Which plan would be recommended if the plan is for 2 years?</h3>
Rongers: $127(24) = $3,048
Fidoll = $363 + $94(24) = $2619
I would recommend the Fidoll plan

Cot= cos/sin
<=> cot= [(✔️13^2-5^2)/13]/(5/13)
<=> cot= (12/13)/(5/13)
<=> cot= 12/5
