Answer:
x = 48
Step-by-step explanation:
The sum of the angles in a pentagon is 540°, so you have ...
90° +100° +110° +2x° +3x° = 540°
5x = 240 . . . . . . . divide by °, subtract 300
x = 48 . . . . . . . . . divide by 5

<em>Additional comment</em>
The sum of angles in a convex n-gon is (n -2)×180°. For a pentagon, that's 3×180° = 540°.
Answer:
x=6 y=-5
Step-by-step explanation:
6x+5y=11
X=1-y
6x=6(1-y)
6x=6-6y
6-6y+5y=11
6-y=11
y=-5
x=1-y
x=1-(-5)
x=6
so,
x=6
y=-5
2/5h+g=d first subtract g from both sides 2/5h+g-g=d-g 2/5h=d-g then multiply both sides by 5/2 5/2(2/5h)=(d-g)5/2 h =5/2(d-g)
