Answer:
See Below.
Step-by-step explanation:
We are given:

Using exponent properties:

Rewriting:

Since i⁴ = 1 and i² = -1:

1 to any power is still 1:

Star = 5
square =3
or the other way around
I don’t know the answer I can’t see the question that you are asking for
Using the triangle, we can find the angle lengths and using those and trig ratios, find the side lengths. Lets say the top side length is "y".
Using the Law of triangles, we can find the missing angle from 180-90-70=20 deg.
Then we can use the Law of sines,
sin(70)/13=sin(20)/y
y=sin(20)*13/sin(70)
y=15.34
Finally, we use the Pythagorean Theorem, (13)^2+(15.34)^2=x^2
x = 20.1
