Answer:

Step-by-step explanation:
Line 1: (1, a) and (5, −2)
slope of the line is

Line 2: (2, 8) and (−5, a + 7)
slope of the line is

when the lines are parallel then slopes are equal

cross multiply it


subtract 4a from both sides


divide both sides by 3

1. You do 180-88 because supplementary angles add up to 180°.
2. 180-88=92°. Angle 4 is 92°
The area of the shape is 260 square cm
<h3>How to determine the area of the shape?</h3>
The given parameters are:
<u>Triangle</u>
Height = 6cm
Base = 20 cm
<u>Rectangle</u>
Length = 10cm
Width = 20 cm
The area of the shape is calculated as:
Area = 0.5 * Base * Height + Length * Width
So, we have:
Area = 0.5 * 20 * 6 + 10 * 20
Evaluate
Area = 260
Hence, the area of the shape is 260 square cm
