Answer:
False
Step-by-step explanation:
1+16=17
14+2=16
17 does not = 16
Answer:
40.3
Step-by-step explanation:
Use pythagoras theorem, a^2 + b^2 = c^2
400 + 1225 = 1625
sqrt of 1625 = approx 40.3
Alright, so what we can take as a given is that arcDE/2= ∠CDE=2x+20 since the arc corresponding to the angle is 2*the angle. To solve for arcDE, we multiply both sides by 2 to get 2(2x+20)=4x+40=arcDE. Since the arcs in a circle add up to 360 degrees and we only have -20+30x and arcDE, we have -20+40+4x+30x=360 using the associative property. Simplifying, we get 20+34x=340. Subtracting 20 from both sides, we get 340=34x. Next, we can divide both sides by 34 to get 10=x.
Answer:
B I'm pretty sure
Step-by-step explanation:
9 and 4 have 36 in common
to get 9 to 36 you multiply it by 4 and 2x4 is 8
to get 4 to 36 you multiply it by 9 and 1x9 is 9
9+8 is 17
