A circle is shown. 2 chords intersect to form 4 angles. From top left, clockwise, the angles are: 3, 2, 1, 4. Angle 3 intersects an arc with measure 54 degrees. Angle 1 intersects an arc with measure 112 degrees. Marcel is designing a circular necklace that will consist of 4 sections, each with a different color of plastic. Determine how he needs to cut the plastic by finding the measures of the angles. m∠1 = ° m∠2 = °

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
