The net shows an equilateral triangle with side length 24 cm.
The area of an equilateral triangle of side length s is ...
... A = (√3)/4·s²
Using the above side length, the area is
... A = (√3)/4·(24 cm)² = 144√3 cm² ≈ 249.4 cm²
Your best choice is the first one:
... A) 249.6 cm²
Answer: x = -7
Step-by-step explanation: use the slope formula and slope intercept form y = mx + b to find the equation
Divide -4 on both sides then change the greater then sign to less then so it looks like....-x < -3
Answer:
m<B is 48°
Step-by-step explanation:
