Answer:
y = x + 1
Step-by-step explanation:
To find angle BCD, find the angle ACB that lies next to it on the straight line first.
Angles in a triangle add up to 180.
To find angle ACB:
180 - 83 - 47 = 50
So angle ACB = 50.
Angles on a straight line add up to 180 as well.
So to find angle BCD:
180 - 50 = 130
So angle BCD = 130, so the answer is D.
A=3.14(4)(4+sq rt of 3squared + 4 squared)
A=3.14 (4)(4+5)
A= 3.14 (4)(9)
A=113.04
Answer:
10
Step-by-step explanation:
a 4 side polygon has 360° interior angle
120 +120=240
360-240=120
120÷2=60
60÷6=10
