Find the value of each variable. Round your answers to the nearest tenth

j=13.10

k=8.40

Explanation:

First to find k you use

SOHCAHTOA

but using TOA which

tan40°=k/10

tan40°=0.8391

cross multiply

k=0.8391*10

k=8.391

k to the nearest tenth =8.40

Then to find k using the Pythagoras theorem

j^2=10^2 + (8.4)^2

j^2=100+70.56

j^2=170.56

take square root

j=√(170.56)

j=13.06

to the nearest tenth= 13.10
