And answer this question for me. explain it too.

Okay so standard form is basically the answer. once you find the answer, its already in standard form.
exponents-the number above the coefficient (the number attached to the exponent) that shows the number of times you multiply the number.
since the number 3 is attached to the exponent of 3, you multiply the original number by itself 3 times.
3×3×3=27
the sports card collector has 27 baseball cards.
now you must apply this to the other equation.
multiply 4 by itself 3 times.
4×4×4=64.
the sports card collector has 64 football cards.

27 baseball cards...
64 football cards...

21°

Step-by-step explanation:

we know that every single triangle has to equal 180°

we have all 3 angles 90° 34° 35° which equal 159°

so we take 180°-159° and your answer is 21°
