<h2>What is an angle?</h2>
An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs, and sometimes the arms of the angle. There are many daily life examples of an angle, such as cloth-hangers, arrowheads, scissors, partly opened doors, pyramids, edge of a table, edge of a ruler, etc.
<h3>How to solve?</h3>
∠C + ∠D = 180° (consecutive angles)
7x +11 + 7x + 1 = 180°
14x = 168°
x = 12°
m∠e = 7x + 1
= 7(12°) + 1
= 85°

Is by using transitions cuz it allows the reader to understand when there’s a shift in events but also the oder
Step-by-step explanation:
Distance = rate × time
If b is the speed of the boat in still water, and c is the speed of the current, then:
60 = (b + c) × 4
35 = (b − c) × 3.5
Simplifying:
15 = b + c
10 = b − c
Add the equations together:
25 = 2b
b = 12.5
Plug into either equation to find c:
c = 2.5
The speed of the boat is 12.5 km/h, and the speed of the current is 2.5 km/h.
