For this case we have that by definition, the area of a triangle is given by:

Where:
b: It is the base of the triangle
h: It is the height of the triangle
According to the data of the statement we have:

Substituting in the formula we have:

So, the area of the triangle is
Answer:

we know that
Imaginary roots will come in pairs, and so the degree must be even.
therefore
the answer is
options


M< 6 = m< 7 (vertical angles)
11x + 8 = <span>12x – 4
12x - 11x = 8 + 4
x = 12
so
m< 6 = </span>11x + 8
m< 6 = 11(12) + 8
m< 6 = 132 + 8
m< 6 = 140
m<4 = 180 - m<6
m<4 = 180 - 140
m<4 = 40
answer
<span>m<4 = 40</span>
Data? I need the data! Not trying to provoke, but in order to answer this I need data...
You can not work it out because we do not know the shape or the other properties of this poster.
Sorry for not being able to answer it.
