Answer:

= 54.78 square units

Step-by-step explanation:

We can calculate the area of the triangle using the formula;

Area = 1/2abSinθ ; where a and b is the sides making the angle θ.

Therefore;

Area = 1/2 bc sin C

        = 1/2 × 16 × 7 × Sin 78

        = 8 × 7 × sin 78

        <u>= 54.78 square units</u>

The volume of a cuboid is 176cm
IRISSAK [1]

Answer:

.08cm or 0.08cm

Step-by-step explanation:

First of all, we can see that 20mm is in millimeters, not centimeters.

If we convert the ones in centimeters to millimeters, it will result in decimals, which I want to avoid, but you could also do it that way.

There are 10 mm in 1 cm, so I multiply all of the values in cm by 10.

So now, we have that the volume is 1760mm, the length is 110mm, and the width is 20mm.

The formula for the volume of a cuboid is: w*l*h = volume

We have the width, length, and volume, so let's plug it in.

20*110*h=1760

To solve for h:

1. Multiply 20 and 100

2200*h=1760

2. Divide both sides by 2200

h = 1760/2200

3. Divide right side

h = 0.8

Keep in mind that this is in millimeters. In centimeters, it would be .08

Nine fourths minus two thirds
Yuki888 [10]

Answer:

1 \frac{7}{12}  \: or \: 1.583

Step-by-step explanation:

nine fourths is also

\frac{9}{4}

two thirds is also

\frac{2}{3}

subtract,

\frac{9}{4}  -  \frac{2}{3}

L.C.M = 12

\frac{27 - 8}{12}

\frac{19}{12}

1  \frac{7}{12}  \: or \: 1.583
