18.8333333333is the answer
Answer:
![2xyzx^{2} \sqrt[ 0]{xyz}](https://tex.z-dn.net/?f=2xyzx%5E%7B2%7D%20%5Csqrt%5B%200%5D%7Bxyz%7D)
Step-by-step explanation:
simplify the radical by breaking the radicand up into a product of know factors
Part (1):
The sum of the internal angles in any triangle is 180.
This means that:
∠1 + ∠2 + ∠3 = 180
We are given that:
∠1 + ∠3 = 154°
Therefore:
∠2 + 154 = 180
∠2 = 180 - 154 = 26°
Part (2):
Complementary angles are defined as angles that sum up to 90°
Supplementary angles are defined as angles that sum up to 180°
We know that ∠1 and ∠3 sum up to 154°.
This means that they are neither complementary nor supplementary.
Hope this helps :)
