Q13.
1. Consider triangles ACB and DCE. In these triangles,
- given;
- given;
- as vertical angles (by vertical angles theorem)
Hence, triangles ACB and DCE are congruent by SAS postulate.
2. congruent triangles have congruent corresponding sides, so
Answer:
C
Step-by-step explanation:
12x + 9 = 13x + 1
9-1 = 13x - 12x
8 = x
Answer:
Step-by-step explanation:
Triangle CDE is a right angle triangle.
From the given right angle triangle
CE represents the hypotenuse of the right angle triangle.
With ∠C as the reference angle,
CD represents the adjacent side of the right angle triangle.
DE represents the opposite side of the right angle triangle.
To determineTan C, we would apply trigonometric ratio
Tan θ = opposite side/adjacent side. Therefore,
Tan C = 80/39
Tan C = 2.0513
Rounding up to the nearest hundredth, it becomes
2.05
