The answer is C.The area of the triangle in Step 3 should be doubled since there are 2 triangles.
Answer:
x=-2, y=8. (-2, 8).
Step-by-step explanation:
8x+5y=24
y=-4x
----------------
8x+5(-4x)=24
8x-20x=24
-12x=24
x=24/-12
x=-2
y=-4(-2)=8
Answer:
x=8
Step-by-step explanation:
this is an equilateral triangle, which means all sides are equal
if all the sides are equal, all the angles are equal
the three angles are all equal to 60 degrees (180/3 = 60)
7x+4 = 60
subtract 4 from each side
7x = 56
divide by 7 on each side
x = 8
Answer:that is a acute angle therefore it would be less then 90
