Hello :
<span>Hello : let
A(-3,-3) B(5,4)
the slope is : (YB - YA)/(XB -XA)
(4+3)/(5+3) =7/8
an equation is : y=ax+b a is a slope</span>
y = (7/8)x +b
the line through
point (5,4) : 4 = (7/8)(5)+b<span>
<span>b = - 3/8
the equation is : y =(7/8)x- 3/8</span></span>
F(x) = x^4 - 3x^3 + 2x^2 - 2x + 5
(x - 3) is a factor of f(x), if f(3) = 0
f(3) = (3)^4 - 3(3)^3 + 2(3)^2 - 2(3) + 5 = 81 - 81 + 18 - 6 + 5 = 17
Therefore, (x - 3) is not a factor of x^4 - 3x^3 + 2x^2 - 2x + 5

Answer:
Hence, m∠R=95°.
Step-by-step explanation:
We are given that ΔABC is similar to the ΔRST i.e. ΔABC~ΔRST.
Aslo m∠A=6x+17, m∠B=3x+9, and m∠C=37
We know that sum of all the angles of a triangle is 180°.
⇒ ∠A+∠B+∠C=180
⇒ 6x+17+3x+9+37=180
⇒ 9x+63=180 (As 6x+3x=9x and 17+9+37=63)
⇒ 9x=180-63
⇒9x=117
⇒ x=13. (on dividing both side by 9)
Hence m∠A=6x+17=6×13+17=95°
m∠B=3x+9=3×13+9=48°
m∠C=37°
Also as ΔABC~ΔRST so this implies m∠R=m∠A=95°
Hence, m∠R=95°.
