Answer:

45°

Step-by-step explanation:

Corresponding parts of congruent triangles are congruent.

From the congruence statement, we know that ∠R≅∠L; since m∠R = 65, this means that m∠L = 65 as well.

We know that ∠S≅∠M; since m∠M = 70, this means that m∠S = 70.

This gives us two of the three angles of the triangle. The sum of the measures of a triangle is 180°; this gives us

65+70+x = 180

135+x = 180

Subtracting 135 from each side,

135+x-135 = 180-135

x = 45°

Can anyone help me find the (?,?) coordinates? The given shape is a parallelogram.

Sonja [21]

The missing coordinates of the parallelogram is (m + h, n).

Solution:

Given shape is a parallelogram.

Construction: Draw a line joining the diagonals.

<em>In parallelogram, diagonals bisect each other.</em>

Solve it using mid-point formula:

$$\text{Midpoint} =\left( \frac{x_1+x_2}{2}, \frac{y_1+y_2}{2}\right )$

Here $x_1=m, y_1=n, x_2=h, y_2=0$

$$\text{Midpoint} =\left( \frac{m+h}{2}, \frac{n+0}{2}\right )$

$$\text{Midpoint} =\left( \frac{m+h}{2}, \frac{n}{2}\right )$

Using this midpoint find the missing coordinate.

$$\text{Midpoint} =\left( \frac{x_1+x_2}{2}, \frac{y_1+y_2}{2}\right )$

Let the missing coordinates by x and y.

Here $x_1=0, y_1=0, x_2=x, y_2=y$

$$\text{Midpoint}=\left( \frac{0+x}{2}, \frac{0+y}{2}\right )$

$$\left( \frac{m+h}{2}, \frac{n}{2}\right )=\left( \frac{0+x}{2}, \frac{0+y}{2}\right )$

$$\left( \frac{m+h}{2}, \frac{n}{2}\right )=\left( \frac{x}{2}, \frac{y}{2}\right )$

Now equate the x-coordinates and y-coordinates.

$$ \frac{m+h}{2}=\frac{x}{2}, \ \ \ \frac{n}{2} = \frac{y}{2}$

Multiply by 2 on both sides of the equation, we get

m + h = x, n = y

x = m + h and y = n

Hence the missing coordinates of the parallelogram is (m + h, n).

I need help ASAP................................

Anestetic [448]

Answer:

x = -1

Step-by-step explanation:

-2(x - 5) = 12

-2x + 10 = 12 (this is the mistake, -2 times -5 = + 10)

-2x = 12 - 10

-2x = 2

x = 2/(-2)

x = -1
