Answer:
Area of the metal sheet required = 364 square inches
Step-by-step explanation:
Area of the metal sheet required = Surface area of the lateral sides of the vent transition
Since, lateral sides of the vent is in the shape of a trapezoid,
Therefore, surface area of the vent = 4(Surface area of one lateral side)
= ![4[\frac{1}{2}(b_1+b_2)h]](https://tex.z-dn.net/?f=4%5B%5Cfrac%7B1%7D%7B2%7D%28b_1%2Bb_2%29h%5D)
Here,
and
are two parallel sides and
is the distance between these parallel sides.
Surface area of the vent = ![4[\frac{1}{2}(8+5)14]](https://tex.z-dn.net/?f=4%5B%5Cfrac%7B1%7D%7B2%7D%288%2B5%2914%5D)
= 364 square inches
Therefore, area of the metal sheet required = 364 square inches

Step-by-step explanation:
Please mark Brainliest!
First you need to find the area of the floor to know how much wood you need
Area=lengthxwidth, so A=40x14.5 which equals 580 square ft
With a floor that's 580 square ft and the boxes cover 18 Sq ft each then all you have to do is 580/18= 32.222 and because you can't buy .222 of a box you need to round up to 33 boxes
Answer:
As shown in picture, the circle is divided into 2 arcs, one of them is 142 deg.
Then the other one A is 360 - 142 = 218 deg (property of sum of all arcs on circle).
As the property of angle created by a tangent line:
x = (1/2) x arc A = (1/2) x 218 = 109 deg
Hope this helps!
