For the last on you need to set up a proportion with the degrees. You know the arcs add to 360 and that small section is 120 so you set it equal to x over the entire area. X is the answer. The formulas are next to all answers
So your answer would be A. m=8d. Hope this helps :)
An isosceles triangle is a special type of triangle that has two equal sides. Consequently, the two base angles are also equal. Since the interior angles of a triangle should sum up to 180°, the general equation should be
180° = 2*Base angle + Vertex angle
Let the base angle be x. Thus, the vertex angle is equal to
Vertex angle = 4x - 6
Substituting,
180 = 2x + 4x - 6
x = 31°
Vertex angle = 4(31°) - 6
Vertex angle = 118°
Answer:
12
Step-by-step explanation:
18/3=6
If one piece is twice as large as the other, than 18 needs to be divided by 3, making it exact.
Answer:
y=-2/3x-2
Step-by-step explanation: Simple math, plot the points and then find the slope by going down 2 and right 3 making the slope negative and the y intercept -2
