Answers:
M for 1 is: 114
M for 2 is: 34
Why?
First you need to find out what the angle is for the corner to the left of angle 1 to do so
180-135 which equals 45
then to find on you take 180 (the sun of all interior angles in a triangle equal 180) and subtract all the angles give...
180-21-45= 114 (which makes since because angle one is obtuse and so is it)
Now for angle to you need to find the corner that is next to angle 1 to do so you do...
180-114 (because angle equals 114) this equals 66
Then you do 180-66-80 to get angle 2 which equals 34
Hope this helps :D
d is the answer
Step-by-step explanation:
all work is shown and pictured
9!/(8!*(9-8)!)=9
or just use a calculator and use the nCr function
Answer:
BC=20
AE= 18
<ABC= 114 degrees, <DAB=66 degrees
Step-by-step explanation:
To find DAB you subtract 180 from 114
