1+sin²x=2-cos²x
Remenber: sin²x+cos²x=1 ⇒sin²x=1-cos²x
1+sin²x=1+(1-cos²x)=2-cos² x (this is true)

Answer:
Y=4
Step-by-step explanation:
Because the two triangles are congruent you can set the two expressions equal to each other and solve from their.
step 1 ) 8Y = 6Y + 8
step 2 ) isolate the variable to one side 8Y-6Y= 8 => 2Y = 8
step 3 ) solve for Y 2Y/2 = 8/2
Solution Y=4
