T= 60
w=60
because 30+90 gives you 120... and 180-120 gives you 60 so t = 60

and w= 60 because the angle across from it will equal the same

Answer:

C. $132m^3$

Step-by-step explanation:

Height = 4

Length = 6

Breadth = 7

Note : We were asked to find volume of the cuboid

Since, it has a base in the shape of a right angle triangle , we need to find the Area of the trapezium before calculating the total volume.

Step 1

Find the area of the trapezium

Area of a trapezium = $\frac{1}{2} (a+b)h$

$\frac{1}{2} (4+7)*4$

$\frac{1}{2} (11)4\\$

$\frac{1}{2} *44\\= 22$

Step 2

Calculate the volume of the cuboid

Volume of a cuboid =length× breadth × height

In this case , the volume will be our length × Area of a trapezium

V= 6 × 22

V = $132m^3$

The route to an ancient pyramid is 79 miles long.

Nostrana [21]

The route to an ancient pyramid is 79 miles long; if 20 miles is travelled each day for 3 days, the distance travelled in the fourth day would be 19 miles.

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

Let the distance travelled in the first day be 20 miles. If the same time was travelled for 3 days, hence:

3(20) + x = 79

x = 19 miles

The route to an ancient pyramid is 79 miles long; if 20 miles is travelled each day for 3 days, the distance travelled in the fourth day would be 19 miles.

Factor completely. 27x^3-12x

You will have to take 3x common from both terms and your ans should look like this,
3x(9x^2-4)
