What is m to the power of 2 minus 11m minus 60 in product/sum method
Nana76 [90]

m^2 -11m -60 = 0

m^2 -11m =60

(m^2 -11m + 121/4) = 361/4

(m - 11/2)^2 = 361/4

m - 11/2 = + or - 19/2

m = 11/2 + 19/2, 11/2 - 19/2

m = 15, -4

---------------------------------------------------

m^2 -11m -60

(11 +- Square root (121 +240))/2

11/2 +- 19/2

m= 15, -4

----------------------------------------------------

m^2 -11m -60

(m - 15) (m + 4)

m = 15, -4

Ugh, more algebra pretending to be geometry.  Why?

This is a pretty awful instance of the genre, with no units on the constant 16, assumed to be degrees.

The total arc measure in a circle is 360 degrees.  Geometry part over.

3m + 16 + 2m + 3m = 360

8m = 344

m = 344/8 = 43

Arc measures:

Arc 3m+16 = 3(43)+16 = 145°.  The angle subtended by that arc is half that, 145/2=72.5°

Arc 2m=2(43)=86°.  The angle subtended is half that, 43°

Arc 3m=3(43)=129°.  The angle subtended is half that, 64.5°
