X - 2y = 10
-2y = -x + 10
y = 1/2x - 5...slope here is 1/2. A perpendicular line will have a negative reciprocal slope. All that means is flip the slope and change the sign. So our perpendicular slope is -2 (see how I flipped 1/2 over...making it 2/1...and changed the sign..making it -2)

y = mx + b
slope(m) = -2
(2,6)...x = 2 and y = 6
now we sub and find b, the y int
6 = 2(-2) + b
6 = -4 + b
6 + 4 = b
10 = b

so ur perpendicular equation is : y = -2x + 10 <==

50 POINTS!!! The measures of the angles of a triangle are shown in the figure below. Solve for x.
tatyana61 [14]

Answer:

x = 5

Step-by-step explanation:

Add all of the angles together. We know that the third one is 90° because it is a right triangle and the little square indicates a 90° angle.

7x + 16 + 39 + 90 = 180


Simply.


7x + 145 = 180

     -145    -145

7x = 35

/7      /7

x = 5

Perimeter of a triangle = Sum of all the three sides of a triangle

  • Perimeter = 3a
  • where, a is the length of the each sides of a triangle.

⇒ 32 = 3a

⇒ a = 32/3

⇒ a = 10.6
