Answer:
d
Step-by-step explanation:
Literally just plug it in
6(7) + 5(-4) - 42 = 0
42 -20 -42 = 0
-20 = 0
Not a solution.
0.000576 is the right awnser
Answer: The sum of the lengths of any two sides of a triangle must be greater than the length of the third side. Since, 11 + 21 > 16, 11 + 16 > 21, and 16 + 21 > 11, you can form a triangle with side lengths 11 mm, 21 mm, and 16 mm.
Step-by-step explanation:
Answer:
The answer would be 10.8
Step-by-step explanation:
By finding the missing base side on the original triangle (which is 18), we add 10 to that number to find the base side on the second triangle. We can then use the equation "sin(21.04) = x/30" to find the missing length side (21.04 is the degree measurement).
Hope this helps :)
