In a triangle, the three interior angles always add to 180°
m∠R + m∠S + m∠<span>T = 180
</span><span>(2x+10) + (2x+25) + (x-5) = 180
</span>2x+10 + 2x+25 + x-5 = 180
5x + 30 = 180
5x = 150
x = 30
Answer:
Angle b
Step-by-step explanation:
$346/100=$3.46 =1% of $346. So, giving 10% discount we $3.46*90=$311.40
Again, $311.40/100=$3.114, providing, 10% discount we get $3.114*90=$280.26.
The net cost after the series discount is $280.26
