Answer:
108°
Step-by-step explanation:
In order to find the measure of the exterior angle, we first need to solve for a. We know that the sum of a triangles' angles is always 180°.
Now we set up an equation:
180 = 44 + (a + 10) + (180 - 2a)
180 = 44 + a + 10 + 180 - 2a
180 = -a + 234
-54 = -a
54 = a
Because we know that a = 54, we can now solve for the exterior angle:
2(54) = 108
Therefore, the measure of the exterior angle is 108°.
<u>Option D
</u>
<u>Answers: </u>
In the given identities a + 0 = 0 + a will represent the additive identity.
<u>Solution: </u>
The additive identity says that if you add a real number to zero or add zero to a real number, then you get the same real number back. This can be written as,
A + 0 = A
The number zero is known as identity element or the additive identity.
Let us understand the additive property using a example:
Let us consider the case 0 + 40 = 40, here 0 represents the identity value.
When we add zero to real number 40, we get the result as 40 which is the same number.
Hence, on the given options, the value a + 0 = a will represent the additive identity.
