Answer:
Step-by-step explanation:
x has the same value as RT since they are equal sides of the isosceles triangle.
RT is also the hypotenuse of ΔRST - 30°×60°×90° right triangle.
Acoording to the property of such triangles, the ratio of sides is:
We have:
Use the ratio to find the lenght of RT
- 2√3 : RT = √3 : 2
- RT = 2*2√3/√3
- RT = 4
So the value of x is 4 units
The three angles are 45, 75, and 60. The sides across from these angles correspond to the length of the sides. Since 45 < 60 < 75, MN < ON < MO. The answer is therefore C. MN, ON, MO.
Hope this helps!
Answer:
Step-by-step explanation:
there is 15 emperor penguins...they make up 30% of all the penguins
so 30% of all the penguins is 15
let x represent all the penguins
turn ur percent to a decimal
0.30x = 15
x = 15 / 0.30
x = 50 <===== 50 total penguins
Answer:
$35
Step-by-step explanation:
7 customers - 2 who didn't tip = 5 who did tip
$7 from those who did tip * 5 ppl who tipped = $35 earned
I can use a chart by numbers them on the chart because I think 4 should be after the 3
