Answer:

x=63

Step-by-step explanation:

Because we know that the total angle is a right angle (see the square in the top right of the problem), and 25 and x+2 constitute as the only two angles making up the total angle, we can say that 25 and x+2 are complementary, meaning they add up to 90 degrees. We can then write our equation as follows:

25 + (x+2) = 90

27+x=90

Subtract 27 from both sides

x=63

Can someone please answer this I don’t understand!

The coordinates of X are (5, 11).

Solution:

Given points of the line segment are P(2, 2) and T(7, 17)

Let X be the point that partitions the directed line segment PT in the ratio 3 : 2

Using section formula, we can find the coordinate of the point that partitions the line segment.

Section formula:

$$X(x, y)=\left(\frac{m x_{2}+n x_{1}}{m+n}, \frac{m y_{2}+n y_{1}}{m+n}\right)$

Here, $x_{1}=2, y_{1}=2, x_{2}=7, y_{2}=17$ and m = 3, n =2

Substitute these in the section formula,

$$X(x, y)=\left(\frac{3 \times 7+2 \times 2}{3+2}, \frac{3 \times 17+2 \times 2}{3+2}\right)$

$$=\left(\frac{21+4}{5}, \frac{51+4}{5}\right)$

$$=\left(\frac{25}{5}, \frac{55}{5}\right)$

$=(5, 11)$

X(x, y) = (5, 11)

The coordinates of X are (5, 11).

If mean of a b c d is 12 . Find the mean of a b c d and e .if e is 50

MArishka [77]

The mean is the average. If the mean of 4 letter (a,b,cd) is 12, the sum of them would be 12x4 =48

Now add e to the total: 48 + 50 = 98

The mean is the total divided by the quantity:

Mean = 98 /5 = 19.6

A scale model of a house is 1 ft. long. The actual house is 50 ft long. In the model, the window is 1 1/5 in. high. How many fee

stich3 [128]

First, identify the ratio:
1:50 (1 foot on the model is 50 feet on the house)
to find the actual height of the window multiply 1 1/5 by 50
$\frac{6}{5}$ * $\frac{50}{1}$ = $\frac{300}{5}$
300/5 simplifies into 60
the height of the real window is 60 feet
