Question

Help please!
If m<2=40, then m<3+m<4=

Answer 1

sure :) u got a diagram attached wid this question ?

Answer 2

you may take a screenshot and attach the pic if its possible..

Answer 3

oops ! u did that already :)

Answer 4

Nvm whoops

Answer 5

first step :
m<2 and m<5 are vertical angles, so they are equal :
m<5 = 40

Answer 6

next, see that m<3 = 90, and
m<4 = 90-40 = 50

Answer 7

so, m<3 + m<4 = 90+50 = 140

Answer 8

see if that makes more or less sense

Answer 9

Another quick way is to see that 2,3,4 form a straight line :-
m<2 + m<3 + m<4 = 180

m<3 + m<4 = 180 - m<2
= 180 - 40
= 140

Answer 10

both methods give u same answer.
pick which ever u feel easy to digest.. :)

Answer 11

Why do you subtract 90-40? (new to this) is that just basic protocol for this type of problem?

Answer 12

thats a very good question !

Answer 13

i did 90-40, cuz :

m<5 + m<4 = 90

Answer 14

next u going to ask, why is that true ?

Answer 15

thats true, cuz from the diagram we see that there is a 'little square' box at the angle 6.
that 'little square' box means 90 degrees.

Answer 16

that 'little square' makes four right angles.
right angle = 90 degrees.

Answer 17

yah sure :) takes time... but these are easy once u get some practice :)

Answer 18

first two are right
last one is not right

Answer 19

lets see, wheteher <1 + <5 gives us 90 or not

Answer 20

<1 + <5

but <5 = <2 as they are vertical angles

<1 + <2

Answer 21

yes, now look at diagram.
<1 + <2 ... do they make 90 ?

Answer 22

the 'little square' box by 6 makes all four angles 90.

Answer 23

so, the 3rd statement is indeed True

Answer 24

I see! Thank you so much, I actually got practice out of my practice worksheet. I appreciate you taking the time to help me

Answer 25

good :) np... you're wlc :)
