Answer:
what do you need help with?
Given that , Length of Base and Hypotenuse is 12 cm and 24 cm , respectively .
Need To Find : The measure of Angle x .
<em>As </em><em>We </em><em>know </em><em>that </em>,
Cos ∅ = Base / Hypotenuse
ㅤㅤ <u>By </u><u>Substituting </u><u>known </u><u>Values </u><u>:</u>
ㅤ⤀Cos x = 12/24
ㅤ⤀Cos x = ½
ㅤ⤀Cos 60⁰ = ½
Therefore,
Cost = fix cost + hourly cost - discount
Cost = 4* [5 + 4x - 4x(20/100)] = 4*[5 + 4x - 0.8x] = 4*[5 + 3.2x] = 20 + 12.8x
Answer: option B) 12.8x + 20
Your line is wrong from the start. But for the equation:
Answer:
<em><u>2</u></em><em><u>1</u></em><em><u>y</u></em><em><u>d</u></em><em><u>^</u></em><em><u>2</u></em>
Step-by-step explanation:
join the centre to all the vertex,
since this figure is of regular pentagon, it's will form 5 equal triangle of equal area!
now area of one such triangle is
1/2 ×base ×height
=1/2 ×3.5x2.4 (yd^2)
=4.2 yd^2
now the pentagon is sum of 5 such equal triangle,so it's are will be
5×4.2 (yd^2)
=21 yd^2
