Answer:
∠K = ∠M = 55°
Step-by-step explanation:
The two marked angles are opposite the sides marked as congruent. That means the angles are congruent, so we have ...
4x -1 = 2x +27
2x = 28 . . . . . . . . add 1-2x to both sides
x = 14
4x -1 = 4(14) -1 = 55
The measures of the angles are ...
∠K = ∠M = 55°
Answer:
144
Step-by-step explanation:
you're going 40m per hour
so in 3.6 hours,
the equation is 40×3.6=144 miles

Answer:
240°
Step-by-step explanation:
The sum of angles in a quadrilateral is 360°, so you have ...
a° +b° +60° +60° = 360°
a° +b° = 240° . . . . . . subtract 120° from both sides
Answer:
see explanation
Step-by-step explanation:
Slope- intercept form is y = mx + c
Rearrange the given inequalities into this form
x + y ≤ 55 ( subtract x from both sides )
y ≤ - x + 55
-------------------------------------------------
60x + 40y > 600 ( subtract 60x from both sides )
40y > - 60x + 600 ( divide all terms by 40 )
y > - x + 15
