I'm jus gonna guess 94 if right brainliest plzzz
Answer:
Step-by-step explanation:
2 csc²x-2 csc x-1=0
or

The sum of the angles in a triangle is 180, so the equation will be :
2k+k+45= 180
add similar variables
3k+45=180
3k=135 (divide each side by 3)
k= 45
So 2k equals= 90
k=25
This is right angle triangle for your info!
Answer:
Hi! The correct answer is x=1/4+y/2!
Step-by-step explanation:
Solve for the first variable in one of the equations, then substitute the result into the other equation
Area = 10 * 1/2* * 14 * 25 (note decagon has 10 sides)
= 1750
