The value of the variables for x and y that are in the first triangle respectively will be 13 and 18.38.

How to calculate the triangle?

From the information given, the variables can be found by using sine and Pythagoras identity.

Here, tan 45° = x/13.

1 = x/13

x = 1 × 13

x = 13

The value of y will be calculated thus:

y² = 13² + 13²

y² = 169 + 169

y² = 338

y = ✓338

y = 18.38.

The value of y will be 18.38.
