m∠T = 40.4°
Step-by-step explanation:
We know all the sides of the triangle but we do not know any of its angles.
To find out if the angle T = 40.4 ° we use the cosine theorem.
According to the cosine theorem:
Where is the angle between a and b.
In this case:
Then we clear α from the formula and verify that it is equal to 40.4 °
