Find the missing side

Mathematics
1 answer:
Step2247 [10]2 years ago
8 0

Answer:

\huge\boxed{\sf x = 8.2}

Step-by-step explanation:

Since it is a right-angled triangle, we will apply Pythagoras Theorem.

<u>Given are:</u>

Base = 16

Perpendicular = x

Hypotenuse = 18

<u>Pythagoras Theorem:</u>

\sf (Hypotenuse)^2=(Base)^2+(Perpendicular)^2

(18)² = (16)² + (x)²

324 = 256 + x²

Subtract 256 to both sides

324 - 256 = x²

68 = x²

Take sqrt on both sides

8.2 = x

x = 8.2

\rule[225]{225}{2}

PLEASE HELP. IF U GET THIS RIGHT I WILL MARK U BRAINLIEST!!! THANK U GUYS
KatRina [158]

Answer:

2

Step-by-step explanation:

The slope is the rise over the run. 2 simple coordinates I can see is (6,2) and (7,4). I usually like to visualize it instead of actually solving it mathematically. So, we can start at (6,2). The point (6,2) goes up 2 and 1 to the right in order to get (7,4.) So since the slope is rise over run ( y/x) it would be 2/1 because we went 2 up the y axis and 1 to the right of the x axis. So 2/1 is 2. Therefore, 2 is the answer.  I'm sorry if my explaining isn't the best... I hope this helps though!!

5. A pyramid with a triangular base has a volume of 80 cubic meters and a base
ddd [48]

The height of the triangular pyramid will be equal to H=12 feet.

<h3>What is a triangular pyramid?</h3>

A triangular pyramid is a pyramid having triangular faces the other sides of the pyramid are simliar triangles.

It is given that:-

The Volume of the pyramid=80 cubic meters

The Base area of the pyramid=20 square meters

The height of the pyramid=?

We know that the volume of a pyramid is given as:-

V=(1÷3)x Base area x height

V=(1÷3)x20 x H

H=(80x30)÷20

H=12 feet

Hence the height of the triangular pyramid will be equal to H=12 feet.
