Find the value of x and y.

Mathematics
1 answer:
Scorpion4ik [409]3 years ago
8 0

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
