Answer:
x = 45
Step-by-step explanation:
The angles with (2x + 45) and x are supplementary angles, meaning they add up to 180°. We can write this statement as an algebraic equation of
and solve it.
Step 1: Combine like terms.
Step 2: Subtract 45 from both sides.
Step 3: Divide both sides by 3.
Step 4: Check if solution is correct.
Therefore, x = 45.

Answer:
B
Step-by-step explanation:
B is the only one that has only 2 sides of the same length and one that doesn't match the other 2.
A doesn't have any of the lengths being the same
C. is a right triangle, although there can be isosceles right triangles they still need to have only 2 lengths that are the same and in this one, all the values are different
D. This is an equilateral triangle, this has more than 2 lengths that are the same

Answer:
a ≈ 4.68
Step-by-step explanation:
The law of cosines tells you ...
a² = b² +c² -2bc·cos(A)
a = √(b² +c² -2bc·cos(A))
a = √(5² +8² -2·5·8·cos(33°)) = √(25 +64 -80·0.83867) ≈ √21.906
a ≈ 4.68
