Step-by-step explanation:
she’s so amazing and she’s just omg she’s perfect
Answer:
(-2.5,0)
Step-by-step explanation:
1.5(4x+3y)=-10(1.5) =
6x+4.5y=-15
6x+4.5y= 6x-5y (substitution)
-6x from both sides
4.5y =-5y
y=0
6x-0=-15
divide by 6
x=-2.5
Check:
-2.5(4)+3(0)=-10
-10= -10 (correct!)
(6)-2.5-0=- 15 (correct!)
In <span>equilateral triangle all sides are equal =x,
from right triangle that is formed by </span>apothem , height 7*3= 21
hypotenuse /opposite leg = sin angle,
hypotenuse is a side of triangle =x, opposite leg is apotheme =21,
angle in equilateral triangle =60⁰
21/x= sin 60, x*sin60=21, x=21/sin60, x=21/(√3/2), x=42/√3
Area of triangle =1/2 x*x*sin angle
Area of triangle =1/2 *42/√3*42/√3*sin 60=1/2*(42²/3)*(√3/2) ≈ 255 cm²
this is just second way to do this problem, that I did at first (either way is correct)
<span> apothem divides one side by half,
so we get small right triangle with sides x hypotenuse, x/2 is one leg , and 21 is another leg
</span>by Pythagorean theorem
x²=(x/2)² +21²
x²-x²/4=441
3x²/4=441
3x²=441*4=1764
x²=1764/3
x=42/√3
Area of triangle =1/2*base *height =1/2*42/√3 *21≈255 cm²
