Answer:
4.3
Step-by-step explanation:
first round
3.296 is 3.3
0.9785 is 1
3.3 + 1 = 4.3
The measure of angle 1 is 55.
The top angle= 75 because of the vertical angle theorem
The right angle= 50 because of the alternate exterior angle theorem
75+50=125
There are 180 degrees in a triangle so the angle has to equal 55
9514 1404 393
54
The external angle is half the difference of the subtended arcs.
x° = (136° -28°)/2 = 108°/2
x = 54
