Hey can someone please help me with this? I’d appreciate if you put steps down and the answer! Tysm.

Pythagoras Therom a^2 + b^2= C^2

Opposite the right angle is x at the bottom which is the hypotenuse. you only need to work out the bottom triangle so forget the top.

18/2=9 for the bottom length.

9^2 + 20^2 = 481^2 (opposite of squaring)

square root 481 = 21.9317121 rounded up would be 22cm x= 22cm

answer: 12

step-by-step explanation:

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
