expeople1 [14]

Answer: 1852.5 cubic inches

Step-by-step explanation:

The Volume of cuboidal box is given by:-

$Volume=length\times width\times\ height$

Given: The length of box = $9\frac{1}{2}\ inches=\frac{19}{2}\ inches$

The width of the box = $15\ inches$

The height of the box = $13\ inches$

Now, the volume of box is given by:-

$Volume=\frac{19}{2}\times15\times13=\frac{3705}{2}=1852.5\ inches^3$

Trigonometry: <br>1) Work out the bearing from B to C. <br>2) Calculate the bearing of D from B

kakasveta [241]

Answer:

see below

Step-by-step explanation:

a bearing is the angle in degrees measured clockwise from north.

Triangle ABC is a right triangle

Tan C = opp side / hyp

tan C = AB / CA

tan C = 30/30

tan C = 1

taking the inverse tan

tan ^ -1 tan C = tan ^ -1 ( 1)

C = 45 degrees

This is 90+45 degrees from North

135 degrees from north

Tan B = opp side / hyp

tan B = AD/BA

tan B = 45/30

tan B = 3/2

taking the inverse tan

tan ^ -1 tan B = tan ^ -1 ( 3/2)

D = 56.30993247

Add 180 degrees

180+56.30993247

236.3099325 from north

Find the measure of ∠C if

V125BC [204]

$(32x+20) + (72x+20) + (52x+40) + (32x+10)=180 \\ 32x+72x+52x+32x +20+20+40+10 =180 \\ 188x+90=180 \\ -90 \\ 188x=90 \\ /188 \\ x=0.478
$
then $52(0.478)+40 \\ 24.856+40=64.856
$
∠C = 64.856
