Answer 3

@Godlovesme

Answer 4

You can find a by using Pythagorean theorem

Answer 5

then you can find one of the unknown angles by using a trig ratio

Answer 6

then you find the last angle by using that the sum of angle measurements of at triangle equal 180 deg

Answer 7

Ok! thank you @freckles! I hate geometry, algebra is better.

Answer 8

well @GodGirl360 if you want to see if you can find the values yourself
i will be here to check them
but if you feel like you aren't sure what I'm talking about let me know we can try to work together

Answer 9

@freckles
a=12.84
b=146 degrees
c=34 degrees

Answer 10

hmm...
these things look a little off
let's look at the hyp measurement we call a first

Answer 11

\[3.1^2+8.9^2=a^2 \\ \sqrt{3.1^2+8.9^2}=a\]

Answer 12

is this what you did for a?

Answer 13

yes, i realized i did the math wrong while solving it. the answer is 9.42.

Answer 14

sounds great for a

Answer 15

now lets look at b

Answer 16

I will round a to the nearest tenth since everything else is given in tenths
but you can leave yours as hundredths unless your question says to round to hundredths or whatever
