What is the area of the triangle in the diagram? A.
ivity2 + y 2)(022 + y2?
OB. V ( x 2² – 2₂ ²) (V2² - 4, ?)
oc. √(x² + y, ²) (*2 ² + y ₂2)
D. 2/(x2² – 2x, ²) (y 2² – 4,2)

-2

7 - 9 = -2

reversed:

-2 + 9 = 7

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.

12

step-by-step explanation:

a triangle's   full angle is 180 degrees so 180 - 156 = 24. 24/2=12
