Remember
- Its a dilation so the ratio of corresponding sides remains same like before .
So
- All trigonometric ratios are also same in both traingles
Or
- Hence sine is equal
- So all trigonometric functions are also equal
#B
- cosX=Base/Hypotenuse
- cosA=AC/AB
So
- AC equal to 2.05
- AB=5.59
Remember
(x^m)^n=x^(mn)
and
![x^{m/n}=\sqrt[n]{x^{m}}](https://tex.z-dn.net/?f=%20x%5E%7Bm%2Fn%7D%3D%5Csqrt%5Bn%5D%7Bx%5E%7Bm%7D%7D%20)
(m^(2/3))^(1/2)=m^(2/6)=m^(1/3)
m^(1/3)=∛m
last one (rightmost)
