17 =1.14
18= 276
19= 31.42
20= 150
I think these are all correct
Answer
60
Step-by-step explanation:
105+15= 120
180-120=60
I think this is the correct answer but I dont know
-1 should be what you are after
Answer: Choice 1) 48 degrees
The fact that line m is parallel to line n is irrelevant info for this problem. We know that the angle supplementary to angle 1 is the 132 degree angle. This is because these two angles form a straight (180 degree) angle.
So, x+132 = 180 solves to x = 180-132 = 48
DF would equal 4.92
You would set up a proportion.
I did 4/13=x/16. Then cross multiply and solve for X. And I got 4.923 then round to the nearest hundredth and the answer will be 4.92
