Answer:
C. 8√3/3
Step-by-step explanation:
It can be useful to remember that the ratio of sides in a 30°-60°-90° triangle are ...
1 : √3 : 2
That is the short leg is 1/√3 times the length of the longer leg.
8(1/√3) = 8(√3/3) . . . . . matches choice C
3 times 5 times 2.5 = $37.5
3 x 5 =15
15 x 2.5 =37.5
37.5 x 2 = 75 for both of them
I don't know if this is right or not, but that's how I would solve it!
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
6 times 79 = 474 so the 79th term is 474
