for number 2, "309 – 60°- 900 triangle"? you sure about that?
anyways here's what i found from googling
"If you know one side of a 30-60-90 triangle, you can find the other two by using shortcuts. Here are the three situations you come across when doing these calculations:
Type 1: You know the short leg (the side across from the 30-degree angl...... reply
idk if this is correct but here's what i got
1. 12 cm
solution:
the legs of an isosceles triangle are congruent/equal
2. hypotenuse: 26 cm, other leg: 13(√3) or 22.517 cm
solution:
using special right triangle 30-60-90
to find the hypotenuse:
2*13 = 26
to find the other leg:
13*(√3) = 13(√3) = 22.517
3. (20(√2))/2 cm
solution:
using s...... 1 reply
isn't this 9th grade math stuff lol, uh idk if these are correct but
1.) 12 cm(?)
2.)13 times the square root of 3
3.) 10 times the square root of 2 2 reply
