How would I solve for x?

vaieri [72.5K]

Answer:

$x = 65$

Step-by-step explanation:

First, we calculate the unknown angle of the left triangle and right triangle: $180 - 62 - 50 = 68$

Unknown angle for left triangle⬆️

$180 - 80 - 53 = 47$

Unknown angle for right triangle⬆️

Now we've calculated the two angles for the small triangle in the middle. So, we just have to calculate the top angle of the middle triangle:

$180 - 68 - 47 = 65$

The angle 65° and angle of x are vertical angle.(both are equal)

So... x= 65°

hope it helps :)

Write the standard equation of a circle with center (2, −5) and radius 16.

astra-53 [7]

The standard equation of circle when center is (h,k) and radius is 'r'

$\left ( x - h \right )^{2} + \left ( y - k \right )^{2} = r^{2}$

h = 2 and k = - 5, radius = 16

So equation of the circle is given by

$\left ( x - 2 \right )^{2} + \left ( y - (-5) \right )^{2} = 16^{2}$

$\left ( x - 2 \right )^{2} + \left ( y + 5) \right )^{2} = 256$
