Question

can you solve these problems
(Sina)^2 + (cosa)^2 =
​

Answer 1

Answer:

Sina = perpendicular/ hypotenuse

(Sina)^2 = perpendicular^2/hypotenuse^2

cosa= base/ hypotenuse

(cosa)^2 = base^2 /hypotenuse^2

sina^2+ cosa^2 = perpendicular^2/hypotenuse^2 + base ^2 /hypotenuse^2

( base^2 +perpendicular^2) = hypotenuse^2

= hypotenuse^2+ hypotenuse ^²= 1
