$65\º + (3x-10\º) +(2x) = 180\º \\ \\ 65\º+ 3x-10\º +2x = 180\º \\ \\ 3x +2x = 180\º +10\º -65\º\\ \\ 5x = 125\º \\ \\ \\ x= \dfrac{125\º}{5}\qquad \to \boxed{x= 25\º}$

$B= (3x-10\º) \\ \\ B= 3(25\º) -10\º \to \boxed{B= 65\º} \\ \\ C= 2x \º\\ \\ C= 2*(25\º) \to \boxed{C= 50\º}$

Let f(x)=(18)3^x. find the equation of the line between the points (-2,f(-2)) and (1,f(1))

horsena [70]

$\text{Given that,} \\\\f(x) = 18 \cdot 3^x \\\\f(-2) = 18 \cdot 3^{-2} = 2\\\\f(1) = 18 \cdot 3^1 = 54\\ \\\text{So,}~ (x_1,y_1) = (x_1, f(-2)) = (-2,2) ~\text{and}~ (x_2,y_2) = (x_2, f(1)) = (1,54)\\ \\\text{Slope,}~ m = \dfrac{y_2 -y_1}{x_2 -x_1} = \dfrac{54-2}{1+2} = \dfrac{52}3 \\\\$

$\text{Equation of line,}\\\\~~~~~~~y - y_1 = m (x-x_1)\\\\\\\implies y-2 = \dfrac{52}3(x+2)~~~~~~~~~~~;[\text{Point-Slope form.]} \\\\\\\implies y-2 = \dfrac{52}3x + \dfrac{104}3\\\\\\\implies y = \dfrac{52}{3}x + \dfrac{104} 3 +2\\\\\\\implies y = \dfrac{52}3 x +\dfrac{110}3 ~~~~~~~~~~~~~~~;[\text{Slope -Intercept form}]$
