Let unknown side be x
angle be a
using pythagorus theorem,1²+2²=x²
x²=5
x= √5,-√5
cos a= 2/√5
but a is in quadrant III ,Cos is negative
<h2>cos a= -2/√5</h2>

Answer:
<h2>3 shirts</h2>
Step-by-step explanation:
We need to do several things. I'll put all the steps separate, so you easily follow.
<h3>Step 1: Add up current purchases</h3>
40 + 40 = 80
<h3>Step 2; Set up inequality</h3>
$80 + s <u><</u> $125
<h3>Step 3: Solve the inequality</h3>
s <u><</u> $45
45/15 is 3, so he can buy 3 shirts.
<h3>Step 4: Check</h3>
$80 + $45 <u><</u> $125
$125 <u><</u> $125 ✔
<h3>Step 5: Double Check</h3>
This is an inequality. To make sure we got it right, we need to try another value.
$80 + $32 <u><</u> $125
$112 <u><</u> $125 ✔
<h3>Step 6: Answers</h3>
s <u><</u> $45
3 shirts
I'm always happy to help :)
