Transcribed Image Text:On this educational exercise, students are asked to solve geometrical problems using a diagram of a circle with intersecting lines and tangents.
**Problem Statement:**
Given:
- m∠FAE = 65°
- m∠AFD = 35°
- m∠AB = 60°
- FA and GC are tangent to the circle
Find the following (round to the nearest tenths if necessary):
A. m∠ACG
B. m∠ABD
**Diagram Description:**
The diagram features a circle with a few intersecting lines and segments:
- Points \(A\), \(B\), \(C\), \(D\), \(E\), \(F\), and \(G\) are labeled.
- \(FA\) and \(GC\) are tangent to the circle at points \(A\) and \(C\) respectively.
- Line segments include \(FA\), \(AF\), \(FD\), \(AB\), \(BE\), and \(EG\).
- Angles provided in the problem are shown as:
- \(∠FAE = 65°\), which is an angle formed by the tangent \(FA\) and the intersecting segment \(AE\).
- \(∠AFD = 35°\), which is an internal angle in the triangle \(AFD\).
- \(∠AB = 60°\), which is marked along segment \(AB\).
**Tasks:**
1. Students need to calculate the measure of angle \(∠ACG\).
2. Students need to find the measure of angle \(∠ABD\).
When solving the tasks, students should employ concepts of circle geometry, use tangent properties, and apply the given angle measures effectively.
