55 deg 30 Minutes = 55.5 degrees
sin = opp/hyp
sin(55.5) = altitude/10
Altitude = 10*sin(55.5)
Altitude = 10 * sin(55.5) = 8.241261886
Rounded to nearest 10th
Altitude = 8.2 cm
b. for base use Low of Cosines
Let C = base
Side A and B = length 10 Cm
c^2 = 2*a^2 -2a^2*cos(<C)
<C = 180 - 2*55.5 = 180 -111 = 69 degrees
c = sqrt ( 2a^2 - 2a^2*cos(<C)
c = sqrt ( 2*100- 200*cos(69))
c = sqrt (200 - 200*cos(69) ) = 11.32812474
Answer base
c = 11.3 cms
c.
Area = (1/2)*b * h
Area = (1/2)*(answer a * answer b)
Area = (1/2)* 11.32812474* 8.241261886 = 46.67902132
Area = 46.7 (rounded)
Area = ( 1/2) * a*b*sin(<C) = (1/2)*10*10*sin(69) =
Area = 50* sin(69) = 46.67902132
Area = 46.7 (rounded)</span>
6 and 15 have 3 as a common factor. Thus 6:15 is 2:5. The other ratios are also the same as given in the question. Since the numbers in the second column increase in 15s, the numbers in the first row should increase in sixes (12:30 is the same as 6:15 and 2:5). Thus the answers are:
- 6:15
- 12:30
- 18:45
- 24:60
- 30:75
Answer:
sin(x)= / 12, cos(x)=5/12, tan= / 5
Step-by-step explanation:
segment YZ is length a, we need to find a
segment XZ is length 5
segment XY is length 12
XYZ is a right triangle, so a^2 + b^2 = z^2, so
a^2 + 5^2 = 12^2, simplify
a^2 + 25 = 144, subtract 25
a^2 = 119
a =
then we can determine all the trig ratios
soh - cah - toa
sin = opp/hyp, cos=adj/hyp, tan=opp/adj
sin(x)= / 12, cos(x)=5/12, tan= / 5
Answer:
Step-by-step explanation:
Let L and b be the Length and breadth of Rectangular Piece of sheet metal
also
Square piece of 44 in. is cut from each corner
thus New length of cuboid is
Breadth of Cuboid
Height of breadth is
Volume of Cuboid
substitute the value of L i n volume
