Answer:
20+24= 2(10+12) = 4(5+6)
Those are two ways to factor 20+24.
The answer is 16.5. because of the 2 after the 5, you keep it the same
The area of a triangle is taken by multiplying the length of the base times the height then dividing by 2.
l = 14cm
h = 8cm
A =
A =
A =
A = 56
So first 4x12 then divide that by 7
Those two angles are congruent.
_____
The angles are corresponding parts of congruent triangles (CPCT). Triangles OBA and OCA are right triangles congruent by the HL postulate. The "H" is segment OA. The "L" is the radius, OB or OC. Of course the angles at B and C are 90° as with any radius and tangent line.
