Explore the properties of angles and arcs formed by two intersecting secants.
m2 ABC = 28°
1. Find the difference of arc measures.
MAC = 80°
MAC - mDE = 23
= 56°
mDE = 24°
2. Multiply the angle measure by 2.
2(m_ABC) =

If f(x)=3x+1 and f^-1=x-1/3, then f^-1(7)=

Me solve this problem, and someone clearly explain to me how to solve it.1.) use the value of the discriminant to determine if the given trinomials has 2 real solutions, 1 real solution, or no real solutions. a.  x2  − 4x  − 7 = 0b. 4r2  + 11r  − 3 = 0c. 3m2  + 7 = 0d.  t2  + 2t  + 1 = 0

Use the irregular polygon below. show all work. a. find the perimeter. b. find the area. the angles of the irregular polygon is 2, 8, 8, and 4.
