Answer:

∠ QRS = 43°

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 3 angles and equate to 180

4n - 9 + 5n - 18 + 90 = 180, that is

9n + 63 = 180 ( subtract 63 from both sides )

9n = 117 ( divide both sides by 9 )

n = 13

Thus

∠ QRS = 4n - 9 = 4(13) - 9 = 52 - 9 = 43°

∠ RSQ = 4n - 18 = 4(13) - 18 = 65 - 18 = 47°

What are the coordinates of the centroid of a triangle with vertices P(−4, −1) , Q(2, 2) , and R(2, −3) ?
Alenkasestr [34]

Answer:

(x,y)=(0,\frac{-2}{3})

Step-by-step explanation:

Given : Vertices of Triangle P(x_1,y_1)=(-4,-1) , Q(x_2,y_2)=(2, 2) and R(x_3,y_3)=(2,-3)

To find : Centroid of a triangle

The centroid of a triangle is the point of intersection of the three medians of the triangle.

The formula to calculate the centroid of a triangle is:

(x,y)=(\frac{x_1+x_2+x_3}{3},\frac{y_1+y_2+y_3}{3})

Where, x_1,x_2,x_3,y_1,y_2,y_3  are the coordinates of the centroid

Substituting the values in the formula gives us:

(x,y)=(\frac{x_1+x_2+x_3}{3},\frac{y_1+y_2+y_3}{3})

(x,y)=(\frac{-4+2+2}{3},\frac{-1+2-3}{3})

(x,y)=(\frac{0}{3},\frac{-2}{3})

Therefore, (x,y)=(0,\frac{-2}{3})

Answer:

d < 1

Step-by-step explanation:

First, we have to get d on the same side of the equation. So we will subtract d from both sides and the equation will be  12d-d < + 11. We could also write this problem as d(12-1) < 11, which when simplified would be d(11) < 11. Next, divide both sides by 11 and you get d< 1.   Hope this helps and have a great day!!:D
