What is the unknown angle measure in the triangle?
2 answers:
180 degrees in a triangle therefore you will subtract 54 and 79 from 180 which then gives you the answer --47--
do you understand how to do it now ?
The sum of the interior angles in any triangle is 180 degrees. Using this, we can set up an equation.
54+79+x=180
133+x=180
x=47
The unknown angle is 47 degrees. Hope this helped!

Step-by-step explanation:
Consider ΔKLJ:
sinθ=opposite/hypotenuse
sin30=LJ/8√2
LJ=0.5*8√2=4√2
Consider ΔMLJ:
sinθ=opp/hyp
sin45=x/4√2
1/√2=x/4√2
4√2/√2=x
x=4
