Using the law of sines, it is found that 1 triangle can be formed with the given conditions.
<h3>What is the law of sines?</h3>
Suppose we have a triangle in which:
- The length of the side opposite to angle A is a.
- The length of the side opposite to angle B is b.
- The length of the side opposite to angle C is c.
The lengths and the sine of the angles are related as follows:

Hence, for this problem, we have that the relation is:




G = 54º
A triangle can have one angle of 64º and another of 54º, hence 1 triangle can be formed with the given conditions.

N>9-3 I believe I'm not sure
None of them are like terms you have 5a 5b and 4
Answer:
I believe the second one
Step-by-step explanation:
Because it's angles are all less than 90 degrees so it could be an acute triangle. I am sorry if it is wrong.
we know that
The measure of the interior angle is the half sum of the arcs comprising it and its opposite
so
m∠CED=
see the attached figure with letters to better understand the problem
° ------> by central angle
° ------> by central angle
Substitute the values in the formula above
m∠CED=
m∠CED=
m∠CED=
°
therefore
<u>the answer is</u>
m∠CED=
°
