Answer: Nonliving
Explanation:
It cannot be classified as dead or living as it isn't and never was alive, and it is important to survival and therefore isn't unimportant
Hope this helps!
I assume that it's a hominid fossil - since it has tools and mostly only hominids are found to use tools (although birds are also known to use tools).
It could be Homo erectus, which lived between 2 million years ago and 70 000 years ago, but more likely it's homo habilis, which lived from 2.5-1.5 million years ago.
Answer:
136°
Explanation:
Theorem: The measure of the angle formed by a tangent and a chord is equal to one-half the measure of the intercepted arc.
In the diagram below, PR is the chord, PRS is the tangent, and PQR is the intercepted arc.
Per the theorem,
mPRS = ½mPQR
mPQR = 2mPRS = 2 × 68° = 136°
The measure of the intersected arc is 136°.
