Question

solve for x and y

Answer 1

thats what i wasnt sure of

Answer 2

\[{\sqrt{63}}=\sqrt{x^2}\]

Answer 3

mark one angle as \(\alpha\) , then you need to follow orientation to steup a proportion
once you get it, you will be confident

Answer 4

keep going, simplyfy the radical

Answer 5

\[\sqrt{63}=\sqrt{9*7}\]
\[\sqrt{9}\sqrt{7}\]
\[3\sqrt{7}\]

Answer 6

correct, y you can find using pythagorean

Answer 7

ok let me try that

Answer 8

still, you're clueless in setting up the first proportion, i can see that... we can work on that if you want, after you finish solving y

Answer 9

y^2=9^2+3sqrt7^2


like that....?

Answer 10

yes

y^2=9^2+(3sqrt7)^2

Answer 11

or am i supposed to use the whole triangle

Answer 12

for using whole triangle, you dont know the other leg. So you cant use the whole triangle

Answer 13

ok so i was right the first time
y^2=9^2+(3sqrt7)^2
y^2=81+63
y^2=144
\[\sqrt{y^2}=\sqrt{144}\]
y=12

Answer 14

yes !

Answer 15

i think i got it now :DDDD

Answer 16

good :) more you do more confident you wil feel gotta run, cya
