Answer:
Step-by-step explanation:
Center (0,0)
radius = √16 = 4
A) 180-125 =55
B) both bottom angles are 55 and the triangle's angles should add up to 180, so 55 + 55 + x = 180. X = 70
C) CAE and CBD are equal so the bottom angle (that was calculated in A) will be the base acute angle —>55
Answer: x = 1
Step-by-step explanation:
2.8 + 2x = 0.6 x 8
2.8 x + 2x = 4.8
2x = 4.8 - 2.8 (subtract 2.8 on both sides)
2x = 2
x = 1 (divide 2 on both sides)
Hope this helps
The formula for circumference is pi(diameter) or 2 x pi x radius. So you have the diameter which is 4.25. Next step you need to do is multiply it with pi which is equal to 3.14. Your equation would be C= 3.14 x 4.25.
