Answer:

4cm^2

Step-by-step explanation:

First we need to find the length of the height of the triangle using Pythagoras:

a^2+b^2=c^2 (Substitute in what we have)

a^2+3√2(^2)=2√5(^2) = a^2 + 18 = 20 -> 20-18=2 √2=BD

Now we can find the area:

AD+DC= 3√2 + √2 = 4√2 x √2 = 8/2 = 4

A square pyramid has side lengths each measuring 8 centimeters. The height of the pyramid is 3 centimeters. What is the lateral

Blababa [14]

The lateral area of the pyramid is 108.49 cm^2. The lateral surface area is the total of all of each side's area of a three-dimensional figure and it has a different method to calculate it. First, you must find the triangle's height by using the Pythagoras formula resulting 7.41 cm ( =squareroot(8^2-3^2)), thus, you can find the lateral area using the square and triangles area formula (108.49=(8*8) + 4*(0.5*3*7.41))<span>.</span>

A boy starts from walking North at a speed of 1.5m/s and a girl starts walking West at the same point, P at the same time at a s

prisoha [69]

Answer:

15m

Step-by-step explanation:

For every second, the boy walks 1.5 m

So 6 x 1.5 m equals 9 m total

For every second, the girl walks 2m

So 6 x 2 m equals 12 m total

The boy walked North, so it would look like he is walking upward

While the girl walking West looks like she is walking to the left

Finding the distance between them would look like solving a right triangle

We're gonna use the Pythagorean theorem

12² + 9² = distance²

144 + 81 = 225

√225 = 15
