No, equilateral triangles and isosceles triangles are 2 different things, equilateral triangles have all equals sides and angles (all angle measurements would be 60 degrees) and isosceles triangles have only 2 sides of equal measurements and one is different from the other 2. Hope I helped :)

Hope this helps you. I apologize if it’s incorrect.
Subtract 6 from 10 and your answer is x<4
Dy/dx= tanx, can be answered directly using the derivatives of trigonometric functions but this is how the answer is derived
=(sinx/cosx) basic trigonometric function
= [cosx cox+sinxsinx]/cos^2x
=[cos^2x+sin^2x]/cos^2x
cos^2+sin^2x = 1 ; fundamental trigonometric identities
= 1/cos^2x; reciprocal relations
= sec^2x+C
The answer is letter B.sec^2x+C
a, b y c, d son iguales entre sí porque a es similar ab y si miras las líneas más de cerca, puedes ver que son iguales entre sí. Que tengas un buen día ... lo siento si no hablas español. :D
