X+75+x+125=180
2X+200=180
2X= -20
X = -10
Answer: 45
Step-by-step explanation:
As we can see here, the relation is as follows:
(1)(4)+1 = 4+1= 5
(2)(5)+2 = 10+2 =12
(3)(6)+3 = 18+3= 21
Then, if we follow the same pattern:
(4)(7)+4 = 28+4= 32
Hence:
(5)(8)+5 = 40+5=45
M+(-12)=-8
m-12=-8
m=-8+12
m=4
Answer:
A
Step-by-step explanation:
d≈5.09
Using the formulas
C=2πr
d=2r
Solving for d
d=C/π=16/π≈5.09296
A = 29.745
you can use the law of sine
