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

Can someone explain this a little better?
galina1969 [7]

Answer:

i believe 0.67 of a chance

Step-by-step explanation:

since there are two jobs and a chance that he won't get either that's three options. so the denominator is three (as a fraction). there are two jobs so the probability of James getting one of the two is 2/3. 2/3 as a decimal is 0.66666 and keeps going on and on forever. Rounded to the nearest hundredth, 0.666666 is 0.67.
