Family of Curves
A family of curves is a group of curves that are each described by a parametrization in which one or more variables are parameters. In general, the parameters have more complexity on the assembly of the curve than an ordinary linear transformation. These…
XZ Plane
In order to understand XZ plane, it's helpful to understand two-dimensional and three-dimensional spaces. To plot a point on a plane, two numbers are needed, and these two numbers in the plane can be represented as an ordered pair (a,b) where a and b are…
Euclidean Geometry
Geometry is the branch of mathematics that deals with flat surfaces like lines, angles, points, two-dimensional figures, etc. In Euclidean geometry, one studies the geometrical shapes that rely on different theorems and axioms. This (pure mathematics) ge…
Lines and Angles
In a two-dimensional plane, a line is simply a figure that joins two points. Usually, lines are used for presenting objects that are straight in shape and have minimal depth or width.
Question

Can you please help me with this math? I don't understand this one bit. Thanks :)

## Find the Measure of the Indicated Angle ### Problem 21 You are provided with a diagram of two triangles: - **Triangle on the left**: - Angles are 30°, 100°, and an unmarked angle adjacent to the 70° angle of the second triangle. - **Triangle on the right**: - Angles are 60°, 70°, and the angle marked with a question mark (which needs to be determined). ### Problem 22 You are provided with a diagram of three angles forming a larger geometric shape: - **First triangle**: - Angles are 30° and 40°. - **Angle adjacent to the base of the shape**: - Marked as 25°. - The entire configuration is missing one angle, indicated by a question mark, which needs to be determined. Explore these diagrams to find the missing angles using your knowledge of geometry, such as the sum of angles in a triangle, adjacent angles, and other geometrical properties.

The image contains two geometric diagrams related to angle measurements. **Diagram 27**: - The diagram includes a right triangle, indicated by a small square at the lower left angle, showing it is a right angle (90°). - There are several angles labeled: 41°, 109°, and 85°. - One angle is marked with a question mark (?) indicating it is the unknown angle that needs to be determined. - The diagram visually represents the relationships among these angles, possibly focusing on the properties of angles in triangles and intersecting lines. **Diagram 28**: - This diagram consists of a complex figure with multiple intersecting lines. - Several angles are labeled: 37°, 52°, 62°, and 85°. - Similar to the first diagram, there is an angle indicated by a question mark (?) which needs to be solved. - The angles illustrate concepts such as adjacent angles, vertical angles, and linear pairs. Both diagrams are designed to teach the properties and calculations of angles within intersecting lines and triangles. The question marks prompt learners to apply the concepts of angles to find missing measurements.
