Question

the movement of the progress bar may be uneven because questions can be worth more or less (including zero) depen look at ∠uvy and ∠yvw in the image below. which of the following is the best description for this pair of angles? ○ complementary ○ supplementary ○ straight ○ acute

Explanation:

1. Observe that $\angle UVY$ is marked as a right angle ($90^\circ$).
2. The straight line $UW$ means $\angle UVW = 180^\circ$.
3. Calculate $\angle UVY + \angle YVW = 90^\circ + \angle YVW = 180^\circ - \angle UVX$. Since $\angle UVY$ is $90^\circ$, $\angle YVW$ must be less than $90^\circ$, and their sum is $90^\circ$.
4. By definition, two angles that add up to $90^\circ$ are complementary.

Answer:

complementary
