Answer:
1.2
2.4√3÷3
3. x=45, y=15
Step-by-step explanation:
OK,
1. So the first part requires the Pythagoreanism formula which is: b²=a²+c²:
AC²=AB²+BC²====> AC²=(1)²+(√3)²===> AC²=4===> AC=2
2.The second part requires the formula of tan:
tan A=BC÷AB===> tan A=√3÷1===> tan A=√3
tan C=AB÷BC===> tan C=1÷√3===> tan C=√3/3
tan A+tan C=√3+√3/3===> 4√3÷3
3.And the last part requires the equation of angles:
A+B+C=180===>
x+y+x-y+90=180===> 2x=90===> x=45, y=15
First, we'll need the area of a single triangle
then we'll multiply that by 3 to get our answer
to find the are of a triangle, we multiply height times base then divide that by 2
so.. 5 x 10 = 50; 50/2 = 25
if 25 = one triangle
then 25 x 3 = 75 = three triangles
answer - 75 sq. in.
Answer:
8π in^2 or 25.13 in^2 to the nearest hundredth.
Step-by-step explanation:
The total area = π * 8^2 = 64π in^2
so each slice has an area of 8π in^2.
Answer:
1/9
Step-by-step explanation:
Becuase there are 9 people invited, so they all have a 1/9 chance
30% you have to find a equivalent number with the denominated 100z multiply both numerator and denominator by 100. 120/400x100/100= (120 x 100/400) x 1/ 100=30
