angle 7 is 115°
Step-by-step explanation:
angle 1 is Alternative Exterior Angles, that means they are exactly the same.
step-by-step explanation:
given perimeter: 28cm
length: 9cm
atp,
2(l+w)=p of the reactangle
2(9+x)=28
18+2x=28
2x=28-18
x=10/2
x=5
therefore width is 5 cm
the aswere is the one with all 8's and the second one is with the 10,8 and 6
