Question

PLEASE HELP

Answer 1

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

$\\ \rm\hookrightarrow \dfrac{AB}{BC}=\dfrac{XZ}{YZ}$

• 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
