All angles in a triangle sum to 180°, so
(7x - 8) + (3x + 3) + (18x - 11) = 180
28x - 16 = 180
28x = 196
x = 7
(18x - 11) is the clearly largest angle
18(7) - 11 = 115°
115° is an obtuse angle, therefore the triangle is obtuse

Step-by-step explanation:
Given the following coin values ;
A) 1/2 B. 3 cents C. 20 cents D. $2 1/2 E. $5, state it's worth as a percentage of $1
A) $1/2 as a percentage of $1
$1/2 = $0.5
($0.5/ $1) × 100% = 50%
B) 3 cent as a percentage of $1
3 cent = 3/100 = $0.03
($0.03/$1) × 100% = 3%
