To solve this problem you must apply the proccedure shown below:

1. You have that the ratio of the measures of the three angles is 3:8:9

2. The sum of the interior angle of a triangle is 180degrees

3. Let's say that the measure of each angle is x multiplied by the ratio. Therefore, you can write the following equation and solve for x:

3x+8x+9x=180\\ x=9

4. Therefore, the measure of each angle is:

3(9)=27degrees\\ 8(9)=72degrees\\ 9(9)=81degrees

The answer is: 27degrees, 72degrees,81degrees

What is the Value of x?
Ronch [10]

Answer:

x=8

Step-by-step explanation:

Since this is an isosceles triangle <A is equal to <C

<A = <C = 69

<A+ <B +<C = 180  because the 3 angles of a triangle add to 180 degrees.

69 + 5x+2 + 69 = 180

Combine like terms

140+ 5x = 180

Subtract 140 from each side

140-140 +5x =180-140

5x = 40

Divide by 5

5x/5 =40/5

x=8

Write an equation of the line perpendicular to the given line that contains P.
Yakvenalex [24]

Answer:

  y +5 = -1/3(x -3)

Step-by-step explanation:

The slope of the given line is 3. The slope of the perpendicular line is the negative reciprocal of that, -1/3. Then the point-slope equation is ...

  y -y1 = m(x -x1) . . . . line with slope m through point (x1, y1)

  y -(-5) = -1/3(x -3)

  y +5 = -1/3(x -3)
