Answer:
Step-by-step explanation:
take angle C as reference angle
using cos rule
cos C=adjacent/hypotenuse
cos C=21/75
cos C=0.28
C=
0.28
C=73.7 degree
Answer:
Move all terms to the left side and set equal to zero. Then set each factor equal to zero.
b

Reflex angle because straight is 180 and right is 90 and acute is less than 90
Answer:

Step-by-step explanation:
we have

Solve for m
That means-----> isolate the variable m
Factor the variable m in the equation
![g=m[4c-3]](https://tex.z-dn.net/?f=g%3Dm%5B4c-3%5D)
Divide by (4c-3) both sides

Rewrite

Hello,
P(x)=x^3+2x²-23x-60
P(-4)=(-4)^3+2*(-4)²-23*(-4)-60=0
P(-3)=(-3)^4+2*(-3)²-23*(-3)-60=0
P(5)=5^3+2*5²-23*5-60=0
