97.

9 has a 9 in its tens digit, and a 7 in its ones digit, which is 2 less than 9.

Veseljchak [2.6K]

Answer:

Step-by-step explanation:

∠5 +∠6 +∠7 = 180 {straight line angle}

38 + 62 + ∠7 = 180

100 +∠7 = 180

∠7 = 180 - 100

∠7 = 80°

l // m

∠3 = ∠7 {Alternate interior angles are congruent}

∠3 = 80°.

Write an equation of the line that passes through the given points.

Ratling [72]

$(\stackrel{x_1}{-1}~,~\stackrel{y_1}{4})\qquad(\stackrel{x_2}{4}~,~\stackrel{y_2}{-1})\\\\\\% slope = m\stackrel{slope}{m}\implies\cfrac{\stackrel{rise}{\stackrel{y_2}{-1}-\stackrel{y1}{4}}}{\underset{run}{\underset{x_2}{4}-\underset{x_1}{(-1)}}}\implies \cfrac{-5}{4+1}\implies \cfrac{-5}{5}\implies -1$

$\begin{array}{|c|ll}\cline{1-1}\textit{point-slope form}\\\cline{1-1}\\y-y_1=m(x-x_1)\\\\\cline{1-1}\end{array}\implies y-\stackrel{y_1}{4}=\stackrel{m}{-1}[x-\stackrel{x_1}{(-1)}]\\\\\\y-4=-1(x+1)\implies y-4=-x-1\implies \blacktriangleright y = -x+3 \blacktriangleleft$
