Ratios
A ratio is a comparison between two numbers of the same kind. It represents how many times one number contains another. It also represents how small or large one number is compared to the other.
Trigonometric Ratios
Trigonometric ratios give values of trigonometric functions. It always deals with triangles that have one angle measuring 90 degrees. These triangles are right-angled. We take the ratio of sides of these triangles.
Question
Transcribed Image Text:**Problem Statement:**
Given that \( m\angle Y = 49^\circ \), find the measures of angles \( a \) and \( b \).
**Diagram Explanation:**
The diagram consists of a set of intersecting lines forming several angles. There is one vertical line and one horizontal line intersected by a diagonal line.
- \( \angle Y = 49^\circ \) is labeled on the lower portion of the diagram near the intersection of the lines.
- Angle \( a \) is located adjacent to \( \angle Y \) on the diagonal line.
- Angle \( b \) is formed on the opposite side of the horizontal line that intersects the diagonal line, and it is a right angle indicated by a small square, therefore \( b = 90^\circ \).
**Task:**
Determine:
- \( m\angle A = \)
- \( m\angle B = \)
