Answer:
1 A. 1080°
1 B. 142°, 74°,74°, 125°, 125°
Step-by-step explanation:
1A.
The sum of the measure of the interior angle of a convex octagon is given as
S = (n-2)180°................. Equation 1
Where n = 8 sides
S = (8-2)180°
S = 6×180°
S = 1080°
1B.
The sum of the angle of a convex pentagon is given as
S = (5-2)180°
S = 3×180°
S = 540°
From the diagram,
2x+142+2x+(3x+14)+(3x+14) = 540
10x+170 = 540
10x = 540-170
10x = 370
x = 37°
Hence,
∠H = ∠K = 2(37) = 74°,
∠M = ∠L= (3×37)+14 = 111+14 = 125°

Answer:
Exactly one solution.
Step-by-step explanation:
2x-4y=8
x+2y=4 /*2
<em>2x-4y=8</em>
<em><u>2x+4y=8 (+)</u></em>
4x=16
x=4
4+2y=4
y=0
(x;y)={(4; 0)}
Exactly one solution.
