How do I find the side lengths for this triangle if only one side and ond angle is given? Plz help
1 answer:
The two unknown sides are equal to each other so then the two unknown angles are also equal.
A triangle angles add up to 180
36 + 2x = 180
2x = 180 - 36
2x = 144
unknown angles x = 72°
draw line down center of triangle to make two right triangles with side 22/2 = 11. SOH CAH TOA
cos(72) = 11/H
H = 11/cos(72)
H = 35.6
perimeter = 22 + 2(35.6)
perimeter = 93.2 cm
