Shortest side (a) = 58
middle side (b) = 64
longest side (c) = 77
the 3 sides a + b + c = 199
b = a + 6
c = a + 19
substitute your new values for b & c into your original formula, so:
a + (a+6) + (a+19) = 199
3a + 25 = 199
3a = 174
a = 58
then substitute 58 into your b & c formulas to figure out the rest
b = a + 6 = 58 + 6 = 64
c = a + 19 = 58 + 19 = 77
Answer:
y = 70°
Step-by-step explanation:
4x - 50 and 2x + 30 are equal, because they are corresponding angles
4x - 50 = 2x + 30
4x = 2x + 80
2x = 80
x = 40°
The angle below 2x + 30 = y, because they are vertical angles
Since we know what x is, we can substitute x from 2x + 30
And since two angles that take up a line are 180°, we can add them
2(40) + 30 + y = 180
80 + 30 + y = 180
110 + y = 180
y = 180 - 110
y = 70

Answer:
$7.50
Step-by-step explanation:
$42 × 3 = $126
$27 × 5 = $135
$126 + $135 = $261
$275 - $261 = $14
$14 - $6.50 = $7.50
