Not sure tho
Answer:
see the explanation
Step-by-step explanation:
First way
we know that
The sum of the interior angles of a triangle must be equal to 180 degrees
so
In this problem
37+97+134 > 180
therefore
At least one of Franklin's measures is incorrect
Second way
we know that
A triangle can only have at most one obtuse internal angle.
In this problem the triangle has two obtuse internal angles
Remember that an obtuse angle is an angle greater than 90 degrees
therefore
At least one of Franklin's measures is incorrect
Answer:
AC = 18
Step-by-step explanation:
Using the cosine ratio in the right triangle and the exact value
cos30° = , then
cos30° = = = = ( cross- multiply )
2 AC = 12 × = 12 × 3 = 36 ( divide both sides by 2 )
AC = 18
Answer:
Number 1 does not 2 and 3 do
Step-by-step explanation:
This is because 1 doesn't pass the vertical line test but 2 and 3 do
