Answer:

70

Step-by-step explanation:

we have the angle of vertex in the isosceles triangle = 180-2*bottom coner= 180-65/2=50

3 angles in the equilateral triangle are equal to 60

we have 50 + 60 +h =the angle of PQR =180

h=70

Can anyone help me find the coordinates (?,?) given that the shape is a parallelogram? (15 points)
xxTIMURxx [149]

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

Solution:

Diagonals of the parallelogram bisect each other.

Solve 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

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

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

<u>To find the missing coordinate:</u>

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-coordinate.

$ \frac{m+h}{2}=\frac{x}{2}

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

m + h = x

x = m + h

Now equate the y-coordinate.

$\frac{n}{2} =  \frac{y}{2}

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

n = y

y = n

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

How do you solve these problems?
Rzqust [24]
A)

\bf log_4(x)=3\\\\&#10;-----------------------------\\\\&#10;log_{{  a}}{{  a}}^x\implies x\qquad \qquad &#10;\boxed{{{  a}}^{log_{{  a}}x}=x}\impliedby &#10;\begin{array}{llll}&#10;\textit{we'll use this}\\&#10;\textit{cancellation rule}&#10;\end{array}\\\\&#10;-----------------------------\\\\&#10;4^{\cfrac{}{}log_4(x)}=4^3\implies x=4^3

b)

\bf 3^{2y}=81\qquad &#10;\begin{cases}&#10;81=3\cdot 3\cdot 3\cdot 3\\&#10;\qquad 3^4&#10;\end{cases}\implies 3^{2y}=3^4\impliedby &#10;\begin{array}{llll}&#10;\textit{same base}\\&#10;exponents\\&#10;must\ be\\&#10;the\ same&#10;\end{array}&#10;\\\\\\&#10;2y=4\implies y=\cfrac{4}{2}\implies y=2
