Let the shared side be $y$. Then, $\sin 39^{\circ}=\frac{y}{7} \implies y=7 \sin 39^{\circ}$ \ \ $\implies \tan 55^{\circ}=\frac{7 \sin 39^{\circ}}{x}$ \ \ $x=\frac{7 \sin 39^{\circ}}{\sin 55^{\circ}} \approx 5.4$

Its alr bro thanks

i managed to do it without help

[molten sandal]

👍

In the future, please indicate if you already solved the question tho

so ppl don't bother answering a question that doesn't need to be answered

[main dragon]

Yeah mb i just finished rn haha

was a headache because of the site

[molten sandal]

👍

[main dragon]

i had to round 0.1

for some reason

[molten sandal]

well it does say 1 dp so yeah lol

[main dragon]

nah but when i did it

its was like -0.1 whole number

so if i rounded it to 1dp, 5.6 it would be like 5.7 or 4.7 or 4.6

weird

[molten sandal]

5.6 is already to 1 dp tho

did you round in between

that may be why

[main dragon]

so when doing it in the calculator

i did a shortcut

but it doesnt always work

so i think thats why

[molten sandal]

🤷‍♂️

[main dragon]

here i did 7sin 39/tan (55)

unless i was meant to do somth else?

still confused icl

[molten sandal]

that's fine, idk then, maybe your calculator was in the wrong mode or smthn?

[main dragon]

no i checked its in mode 1

[molten sandal]

idk then

[main dragon]

its ok
