Trigonometry or smth 1. If a leg of an isosceles triangle is 12 cm, what is the measure of the other leg? 2. Find the longer leg of a 309 – 60°- 900 triangle if the shorter leg is 13 cm. 3. In a 45° - 450- 90° triangle, find the measure of each leg if the opposite of 90° angle is 20 cm.
Give answers with solutions ´･ᴗ･`
Whoever answers all right get Idk free webcomic account with 8k coins
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:
