Answer:
X = 50
Step-by-step explanation:
(5x - 100) + (x - 20) = 180 (sum of angle on a straight line is = 180)
5x + x -100 -120 = 180
6x - 120 = 180
6x = 180 + 120
6x = 300
x = 300/6
x = 50
For y
3y + y + 140 = 180
4y = 180 -140
4y = 40
y = 40/4
y = 10
Answer: B
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
slope: (7-3)/(-3-3) = 4/(-6) = -2/3
y = -2/3 x + b
7 = 2 + b
b= 5
y = -2/3 x + 5
Let: s1 = one of the sides of the larger figure
: s2 = one of the sides of the smaller figure
: p1 = perimeter of the larger figure
: p2 = perimeter of the smaller figure
s1/s2 = p1/p2. The ratio of the corresponding sides is the same as the perimeter of the figures.
p1 = 30 + 30 + 35 + 5 + 10 = 110
s1 = 30 and s2 = 18
p1 = 110 and p2 is ?
s1/s2 = p1/p2
30/18 = 110/?
Crisscross ==== 30*? = 18*110
30*? = 1980
Divide both side by 30 ==== 30*?/30 = 1980/30
? = 66
