The ratio of the measures of the acute angles of a right triangle is $8:1$. In degrees, what is the measure of the largest angle

victus00 [196]

Answer:

The angles in the triangle and 10, 80 and 90

Step-by-step explanation:

The two angles that are left in a right triangle add to 90 degrees

8:1 means that there total is 9

8x+1x = 9x

9x = 90

Divide by 9

9x/9 = 90/9

x = 10

8*10 = 80

1*10 = 10

The angles are 80 and 10

The angles in the triangle and 10, 80 and 90

Answer:

$y = \frac{3}{4} x - \frac{3}{2}$

Step-by-step explanation:

$y = \frac{3}{4} x - 1→y - y1 = m( x - x1)$

$y - 6 = \frac{3}{4} (x - 6)→y - 6 = \frac{3}{4} x - 6$

$2(y - 6) = 2( \frac{3}{4} )(x - 6)$

$2y - 6= \frac{3}{2}( x - 6)$

$2y - 6 = \frac{3}{2} x - 9$

$- 6 \: from \: both \: sides$

$2y = \frac{3}{2} x - 3$

$divede \: by \: 2 \: on \: both \: sides$

$y = \frac{3}{4} x - \frac{3}{2}$

Hope this helps!
