Answer:
∠95
Step-by-step explanation:
Hello There!
the measure of supplementary angles add up to equal 180
so to find an angle that is supplementary to angle 85 we subtract it from 180
180-85-95
so an angle that is supplementary to angle 85 would have a measure of 95 degrees
Answer:
180-56=124 ؟ not sure tho hope it helps
Step-by-step explanation:
It has reflection and rotation symmetry
Answer:
12cm
Step-by-step explanation:
Width = 10 cm
Area = 120 cm²
Length = ?
Area = Length(L) × Width(W)
120cm² = L × 10cm
L = 120cm² ÷ 10 cm = 12cm
Hello,
4x²-x-3=0
==>(2x)²-2*1/2*x+1/4-3-1/4=0
==>(2x-1/2)²-13/4=0
==>(4x-1)²-13=0
==>(4x-1-√13)(4x-1+√13)=0
==> x=(1+√13)/4 or x=(1-√13)/4
