Question

10. If a triangle has an angle of 45° and an angle of 100°, what is the third angle?

Answer 1

Answer:

So, 35 degrees is your answer.

Step-by-step explanation:

180 - 100 - 45 = 35 degrees

Answer 2

For this case we have by definition, that the sum of the internal angles of a triangle is 180.

Then, they tell us that two of the angles measure 45 and 100 degrees respectively. If "x" is the missing angle we have:

$45 + 100 + x = 180$

Clearing the value of "x":

$x = 180-45-100\\x = 35$

So, the missing angle is 35 degrees

ANswer:

35 degrees
