5 · 5 - 4 · 4 = 9 sorry if I'm wrong
the dots mean to multiply
Equation~ 5b + (2b - 4) + (3b -6)= 180.
Answer:
23
Step-by-step explanation:
2+2+3+4+5+6 = 23
<h2><u>We can solve it using trigonometric values.</u></h2>
<h3>So , <u> </u><u>sin</u><u> </u><u>θ</u><u> </u> = ( Perpendicular / Hypotenuese )</h3>
<h2><u>Given</u><u> </u></h2>
Perpendicular = x
Hypotenuese = 30


<h2>∴ x ( Perpendicular)= 15√2 <u>Ans</u><u>.</u></h2>
