Answer:
y = 22°
Step-by-step explanation:
the sum of the interior angles of a triangle is 180 degrees
40 + 2x = 180
2x = 140
x = 70
'x' and '5y' form a linear pair, meaning they add up to 180 degrees
x + 5y = 180
substitute 70 for 'x'
70 + 5y = 180
5y = 110
y = 22
Answer:
$2.30
Step-by-step explanation:
The original price is $2.30 an it goes up by 100% which means another 2.30. So add 2.30 and 2.30 together you get 4.60 now divide that by two since the magazine is 50% off and you get the original price which was 2.30
Answer: 12%
Step-by-step explanation:
Total number of people in 6th grade: 70+80 = 150
Total numbers of lefties: 11 + 7 = 18
Percent:
18 ÷ 150 = 0.12
0.12 x 100 = 12
The size of the 4th angle is 72.
Given:
1st angle = 148
2nd angle = 104
3rd angle = 36
shape = quadrilateral.
A quadrilateral is a shape that has 4 sides or edges, 4 corners or vertices.
It goes to show that it must also have 4 angles. These four angles must give the sum of 360°.
Since the first three angles are given, we can get the fourth angle by deducting the sum of the three angles from 360°
4th angle = 360° - 148° - 104° - 36°
= 360° - 288°
4th angle = 72°
Answer:
No plus means addition so it's two
one times one would be 1
but one plus one is 2
