Answer:The answer would be b
Step-by-step explanation:
Answer:
1.
a = 112
b = 68
c = 68
2.
a = 127
3.
a=35
b=40
c=35
d=70
4.
a= 30
b=70
c = 30
d=70
e = 130
I'll help you with the rest later
Step-by-step explanation:
a = 112 because of allied angles rule
b and c = 68 because of angles at a point
360-112-112 ÷2
2. a = 127 because of angles on a straight line rule.
180-38-15
3. d= 70, vertically opposite angle
using angles on a straight line, 180 - 70 - 40 ÷ 2
we now have the two angles and because they are vertically opposite a and c = 35
b = 40 because of vertically opposite angles
4. a=30 because 90-70
since a=30, take 90 - 30 to get b, 70
d= 70, vertically opposite angles
e = 130 because a+b+c, vertically opposite angles
A. W = L - 10
b. P = 2(L + L - 10)
P = 2(2L - 10)
P = 4L - 20
c. solve
P = 4L - 20
244 = 4L - 20
244 + 20 = 4L
264 = 4L
264 / 4 = L
66 = L or L = 66
Length of the rectangle = 66 mm
d.
W = L - 10
W = 66 - 10
W = 56
Width of rectangle = 56 mm
