Can someone help me asap.

A

Step-by-step explanation:

78 x 30 = 2340

2340/2 = 1170

1170 cm²

Step-by-step explanation:

Area = 1/2 (base * height)

We know that base is 78 cm and the height is 30 cm, so:

Area = 1/2 (78 * 30)

Area = 1/2 (2340)

Area = 1170

Therefore, Area of this triangle = 1170 cm²

Hope this helps!

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:
