Answer: x = 20
Step-by-step explanation:
Right angle = 90
90 - 47 = 43
43 - 3 = 40
40/2 = 20
XZ=XY+YZ
JL=JK+KL
use the trigonometric values table or unit circle to calculate the expression

Answer: h = 30.5
Step-by-step explanation
2h - 49 = 12
+49 +49
Add 49 to both sides. Inverse operation
2h = 61
2h/2 = 61/2
Divide 2 to both sides to get answer. Inverse operation
h = 30.5
Check:
2(30.5) - 49 = 12
61 - 49 = 12
12 = 12
