PLS HELP WILL MARK YOU BRAINLIEST! NO FAKE ANSWERS!!<br> WHAT IS M∠1?

TEA [102]

Answer:

angle 1= $135$ °

Step-by-step explanation:

to find the angle of 1 you should know angle 2, what is angle 2?

angle $45$ ° and angle $1$ are symetrical so they have the same value.

now that we know that angle 2 is equal to $45$ °

then what is angle 1

if the whole line has an angle of $180$ ° and angle $45$ °.

so the equation will be :

$45+x=180$

flip the equation to find $x$ :

$180-45=x$

$180-45=x\\135=x\\x=$ the angle 1 which we found in the given equation is 135

check if my answer is correct is :

$135+45=180\\180=180$

my equation is correct
