Answer:
its D
Step-by-step explanation:
3r+2(12r+7)<5r-8
3r+24r+14<5r-8
27r+14<5r-8
22<-22r
when you devide by a negative the signs flips so
22/-22>-22/-22r
-1>r
A pair of angles with a common vertex and sides that are opposite rays
Answer:
Step-by-step explanation:
length=4×28=112 mm=11.2 cm
three centers form an equilateral triangle each side=2×28=56mm=5.6 cm
to find the height
h=√(5.6²-2.8²)=2.8√3
width=2.8+2.8√3+2.8=5.6+2.8√3=2.8(2+√3)
area=11.2×2.8(2+√3)≈117.03 7cm²≈117 cm²
