Answer: x° is 50°
Step-by-step explanation: The sum of the exterior angles of a polygon is 360.
Add the given exterior angles:
35+50+20+125=230
to find the missing exterior angle, supplementary to x°,
Subtract 360 - 230 = 130
The Sum of Supplementary angles is 180°
x° + 130° = 180°
x = 50
Amy needs three-quarters of a gallon of sparkling water.
2 + 5 + 8 + ... + 41 = 301
Answer:
301
Answer:
Step-by-step explanation:
Given
w + 1 = d...........equation 1
d = 3w ...............equation 2
Now putting d = 3w in equation 1
w + 1 = 3w
3w - w = 1
2w = 1
w = 1 / 2
putting w = 1 / 2 in equation 2
d = 1 / 2 * 3
= 3/2

Answer:
B) 4.5
Step-by-step explanation:
The area of the first figure is 10x
The area of the second figure is 6(x+3)=6x+18
To solve, find the x that makes 10x=6x+18
1) 10x=6x+18
2) 4x=18
3) x=4.5
To check work)
1) 10(4.5)=6(4.5)+18
2) 45=27+18
3) 45=45
