Step-by-step explanation:
it's just a guess but the other side of the triangle is 137 degrees
Answer:
fourth option
Step-by-step explanation:
Using the trigonometric identity
cos²x + sin²x = 1
Divide all terms by cos²x
+
=
which gives
1 + tan²x = sec²x
Option A
Opposite angles in a cyclic quadrilateral add up to 180°
So
her
x and 133 are opposite angles
Part A is done after part B
