Answer:
a = sqrt(c^2 - b^2)
see image.
Step-by-step explanation:
If you square both sides of the equation, you get the Pythagorean Theorem back again.
c = sqrt(a^2 + b^2)
c^2 = a^2 + b^2
Solve for a means to get a all by itself on one side of the equation. Subtract b^2 and then take the square root. See image.
Answer:
13
Step-by-step explanation:
4x-9=×+12. x=1 plug it in and u get 13
Answer:
x = 54
Step-by-step explanation:
These angles are complementary because they add up to 90:
x - 7 + 43 = 90
x + 36 = 90
x = 90 - 36
x = 54
Depends on if you think it is bbg
A polynomial with 3 terms with the placeholder as 12 as highest power
example
x^12+3x+9
another
9x^12+6x^6-x
etc
basically
1. 3 terms
2. highest power of exponent is 12
