Answer:
Step-by-step explanation:
a₂/a₁ = ⅘
This is a geometric sequence with initial term = 5 and common ratio = ⅘
a₇ = a₁(⅘)⁷⁻¹ = 5(⅘)⁶ = 4⁶/5⁵= 4096/3125 ≅ 1.311
Problem 16)
We use ASA (angle side angle) to show the two triangles are congruent. Why ASA instead of AAS? Because the single pair of sides are between the two angles.
--------------------------------------------
Problem 18)
Similar to problem 16, we'll have two pairs of congruent angles, and a pair of congruent sides. However, the sides are NOT between the two angles. So that means we use AAS in this case.

Answer: 1. the negative of the conclusion is true
6 semicircles = 3 circles
The formula of the area of a equilateral triangle:
We have a = |AE| = 3cm. Substitute:
The formula of the area of a circle:
We have 2r = |AE| =3cm → r = 1.5cm. Substitute:
The area of the figure:
