The sum of the measures of the angles of a triangle is 180 degrees°. The smallest angle of the triangle has a measure one fourth

vivado [14]

Answer:

8°,32°,140°.

Step-by-step explanation:

Sum of measure of angles of a triangle is 180°

Let the second smallest angle be x°

Smallest angle= $\frac{1}{4}$ x

Largest angle= 5 x- 20°

A T Q

x+ $\frac{1}{4}$ x + 5x-20= 180°

$\frac{4x+x+20x}{4}$ = 180+ 20

$\frac{25x}{4}$ = 200

x= $\frac{200}{25}$ × 4

x= 32°'

Smallest angle is 32°

Hence, the smallest angle is $\frac{1}{4}$ x= $\frac{1}{4}$ ×32°= 8°

Largest angle is 5x- 20= 5×32- 20= 140°

What is the equation of the line that passes through the point (-6, 4) and has a slope of -5/6

tangare [24]

Answer:

$y = -\frac{5}{6}x -1$

Step-by-step explanation:

So, we know the slope is -5/6. From here we can write this equation:

$y = -\frac{5}{6}x + b$

In the question they give us both the x and y in this equation (-6,4)

Plug them in to the equation and solve for b:

$4 = -\frac{5}{6} (-6) + b\\4 = \frac{30}{6} + b\\4 = 5 + b \\-1 = b$

Now, we can write the equation as follows:

$y = -\frac{5}{6}x -1$

I hope this helps!!
