96. the sum of the interior angles of a triangle is: *\na 90 degrees\nb 60 degrees\nc 180 degrees\nd 45 degrees.\n93. there are ____________ bones in the human body. *\na 0.4(25)+0.2(50)+0.5(12)\nb 5(65)+10(9)\nc 600 + 0.5(800)\nd 4(25)+2(50)+0.5(12)

Answer

Explanation:

Step1: Recall triangle - angle sum property

The sum of the interior angles of a triangle is a well - known geometric fact. It is always 180 degrees.

Step2: Analyze the second question

The number of bones in an adult human body is 206. Let's calculate each option:

Option A

$0.4(25)+0.2(50)+0.5(12)=10 + 10+6=26$

Option B

$5(65)+10(9)=325 + 90=415$

Option C

$600+0.5(800)=600 + 400=1000$

Option D

$4(25)+2(50)+0.5(12)=100+100 + 6=206$

Answer:

  1. C. 180 degrees
  2. D. $4(25)+2(50)+0.5(12)$
