Step-by-step explanation:
Answer:
Equation 1
6*a = 360°
Equation 2
2*a + 2*b = 360°
a = 60°
b = 120°
Step-by-step explanation:
From the first picture we can see that 6 angles a° made a complete circle, that is, 360°. So:
6*a = 360°
a = 360°/6 = 60°
From the second picture we can see that 2 angles a° and 2 angles b° made a complete circle, then:
2*a + 2*b = 360°
2*b = 360° - 2*60°
b = 240°/2 = 120°
Lets assume the sides of the isosceles triangle are:
Side A: x
Side B: x
Base: x/2
x+x+x/2= 46.8cm
2x+x/2=46.8cm
4x+x=93.6
5x=93.6
x= 18.72
Side A: 18.72cm
Side B: 18.72cm
Base: 9.36cm
The base of the largest triangular flag Sara can make is 9.36cm.
2x+x/2= 46.8cm
Answer:
18
Step-by-step explanation:
when there is a - in front of an expression in parentheses, change the sign of each term in the expression
6+14+(-2)
then calculate the sum or difference
6+14-2= 18
