we know that s = 3, so plug it in.
P = 6(3)
P = 18
perimeter = 18 km
Katrina has read 85% of her book.
Answer:
A
Step-by-step explanation:
tan theta will equal zero if theta = n × pi where n is an integer
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
answer E .
