B
Step-by-step explanation:
it is the only one that has angles that are right next to eachother!
Answer:
GJ
Step-by-step explanation:
The "Side Splitter" Theorem says that if a line intersects two sides of a triangle and is parallel to the third side of the triangle, it divides those two sides proportionally.
In this case, lines EF and HJ are parallel, H is on side EG and J is on side GF; then using the side-splitter theorem:
Step-by-step explanation:
By Pythagoras' Theorem,
we have x² + (x + 2)² = (x + 4)².
=> 2x² + 4x + 4 = x² + 8x + 16
=> x² - 4x - 12 = 0
(The constants are a = -4, b = -12)
=> (x - 6)(x + 2) = 0
=> x = 6 or x = -2
The value x = -2 is rejected as side lengths cannot be negative.
Hence we have x = 6.
=> AB = 6cm, BC = 8cm, AC = 10cm.
P.S. What you see above is the full solution. You just need to type x² - 4x - 12 = 0 in the blank.
The normally had small extended families.
They were a hunter-gatherer community
Sioux and Cheyenne tribes hunted buffalo
They were nomadic and almost completely dependent on buffalo
