Answer:
x = 9.9
y= 11
Step-by-step explanation:
using sin(45)21 = 29.698
3x = 29.698. Divide both sides by 3
x = 9.899. Round to 9.9
In a Right triangle with 45° angles, the legs of the 90° angle are equal. Given 21,
to find the value of y, the equation is
2y -1 = 21. Add 1 to both sides
2y = 22. Divide both sides by 2
y = 11
