Question

Using the Pythagorean theorem, find the measure of the hypotenuse when a = 3.3cm and b = 2.8cm.
A. 4.3cm
B. 6.1cm
C. 7.2cm
D. 8.0cm

Answer 1

do you know the theorem?

Answer 2

and how it works?

Answer 3

nope

Answer 4

Answer 5

\[a^2+b^2=c^2\] is the pythagoras theorem. Plug in and solve.

Answer 6

okay so the theorem is a^2+b^2=c^2 and it only works for right triangles. so you have to plug in the numbers to the correct variable
for example if a=2 and b=4 then c=2 root 5
so try it for this problem

Answer 7

\[3.3cm^2+2.8cm^2=c^2\]

Answer 8

yep and this is where a calculator becomes helpful :)

Answer 9

We showed you what is needed to be plugged in, now find out what 3.3^2 equals and what 2.8cm^2 equals.

Answer 10

b?

Answer 11

after you found those, you should get..
\[10.89 + 7.84 = c^2\]

Answer 12

exactly now solve for c

Answer 13

\[10.89 + 7.84 = 18.73\] now square 18.73

Answer 14

yep and the answer should be 2.3

Answer 15

does that make sense or do u need another example?

Answer 16

The square root of 18.73 is rounded to 4.3.

Answer 17

oops sorry typo

Answer 18

which would be A.

Answer 19

yep!

Answer 21

@jmansedg you should learn how to plug in and solve on your own as you will be using this for the rest of your math career. believe me.

Answer 22

If marc TMH = 268°, find the measure of the corresponding minor arc.
circle Z with radius ZH, diameter MT, and point A opposite point H
A. 90°
B. 268°
C. 134°
D. 92°

Answer 23

@CloverRacer ur completely right...im in precalc and still use the pythagorean theorem

Answer 24

Please do not post questions from your Geometry exam @jmansedg

Answer 25

i am not

Answer 26

@foreverandalways13 I like your username, i'm a swiftie as well :) I am in algebra II and if you forget the slightest thing, your whole 3 page equation is wrong.

Answer 27

In the URL, it says geometry 7 exam..

Answer 28

yeah no kidding! and yay a fellow swiftie!!!

Answer 29

it does that trust me is it not

Answer 30

sorry but if we help u we might get in trouble because thats what it looks like

Answer 31

it is not trust me please

Answer 32

It literally says 'exam' twice in the URL. I'm sure your teacher has gone over this in a teachlet as you attend roads.advancedmathematics.

Answer 33

its kinda a risk i dont want to take...sorry :(

Answer 34

ok
