Question

the angles of from smallest to largest if AB = 21, BC = 14, and AC = 8.

Answer 1

Angles of triangle ABCD from smallest to largest, help please

Answer 2

the largest angle is opposite the longest side
the smallest angle is opposite the smallest side

Answer 3

how can you have a triangle ABCD?

Answer 4

I can help

Answer 5

do you know how to do sin cos tan?

Answer 6

tan=8/14 = b
tan=14/8 = a
90-a-b = c

Answer 7

@RhondaSommer you do not have a right angle triangle
the sum of the angles in a triangle is 180 degrees

Answer 8

whoops your right lol...meant to put 180 :P

Answer 9

you're*

Answer 10

so 180-a-b = c

Answer 11

I meant abc triangle sorry

Answer 12

do you need to calculate the angles?

Answer 13

@RhondaSommer and @Kalin234 when only given the sides of the triangle use the cosine rule

Answer 14

she would if she has to get the angles from largest to smallest or smallest to largest

Answer 15

you dont have to use cos though

Answer 16

after the largest angle then you can use the sin rule to find the others

Answer 17

I have to organize the angles from largest and smalles

Answer 18

Smallest to largest

Answer 19

review the thread

Answer 20

Bc is the smallest

Answer 21

Or ac

Answer 22

that is the smallest side not angle
