Answer:
30 degrees
Step-by-step explanation:
Angle B is an inscribed angle -- its vertex is on the circle and it intersects the circle in two points, <em>A</em> and <em>C</em>.
The measure of an inscribed angle is always one half the measure of the intercepted arc. The intercepted arc has measure 60 degrees, so the measure of angle B is 30 degrees.
Answer:
-2x + 6
8x or 5x + 3 < 9
Step-by-step explanation:
-2x + 6
8x -> x
3/5
5x + 3 < 9 -> x < 6/5
Answer:
11.
Step-by-step explanation:
(2(n-3))-4=12
(2n-6)-4=12 <em>distribute</em>
2n-6-4=12
2n-10=12
2n=12+10 <em>isolate</em><em> </em><em>n</em><em> </em>
2n=22
2n÷2=22÷2
n=11
D. N/88=16
quotient means divisions so the quotient of a number and 88 is n/88.
Answer:Although the Quadratic Formula always works as a strategy to solve quadratic equations, for many problems it is not the most efficient method. Sometimes it is faster to factor or complete the square or even just "out-think" the problem. For each equation below, choose the method you think is most efficient to solve the equation and explain your reason. Note that you do not actually need to solve the equation. a. x2+7x−8=0x
2
+7x−8=0, b. (x+2)2=49(x+2)
2
=49, c. 5x2−x−7=05x
2
−x−7=0, d. x2+4x=−1x
2
+4x=−1.
