The answer is d because when you put the numbers into the equation you get 2 3(1)+(-1) you get 2
20+8(q-11)=-12
20+8q-8•11=-12
20+8q-88=-12
-68+8q=-12 add 68
+68 +68
8q=-12+68
8q=56 divide by 8
/8 /8
q=56/8
q=7 solved for q
C = pi*d; solve for d.
Divide both sides of this eqn by pi: C/pi = d (answer)
Answer:
60 degrees.
Step-by-step explanation:
Since you know that y = 74 because they are vertical angles, and 46 = the angle across from it (there is a theorem for it). Since one line is 180 degrees, and you already know the two sides next to x, which is 74 and 46, you can do 180 - 74 - 46. Your final answer should be 60 degrees.
75% of 225 = 300.
10% = 30
20% = 60
30% = 90
40% = 120
50% = 150
60% = 180
70% = 210
80% = 240
90% = 270
