1+tan^2=sec^2
so, given expression=
(using sin/cos=tan and tan*cot=1)
hence proved
If you're looking for the answers it would be x= 5/4, 2, 11/4
The answer would be 15 because 15 * 4 is 60 so the remaining amount would the amount of red beans there are in the soup
Step-by-step explanation:
Area of Traingle=1/2×b×h
192cm²=1/2×24×h
192cm²=12×h
h=192/12
h=16cm
Hypotenuse ²=Base²+Altitude ²
Hypotenuse ²=12²+16²
Hypotenuse ²=144+256
Hypotenuse ²=400
Hypotenuse =20cm
Perimeter=20+20+24
=64cm
