Answer:
Step-by-step explanation:
eq. of line is y-(-2)=-3(x-6)
y+2=-3x+18
y=-3x+18-2
y=-3x+16
∵(a,7) lies on it.
7=-a+16
a=16-7=9
a=9
Half-perimeter=length+width=width+3+width=43, 2×width=40 so width=20cm and length=23cm.
Step-by-step explanation:
x = 90- 55 = 35
y = 180- x
y= 180 - 35 = 145
z =180- (y +10)
z = 180 - (145 +10)
z = 180-155
z = 25
