Answer
ask your mom or dad jk its $5.40
Step-by-step explanation:
Example 1: The angle is 42 deg and the length of the hypotenuse is 25. The side of length x is opposite the 42 deg angle.
opposite side
Thus, sin 42 deg = -------------------- => 25 sin 42 deg = x = opp side
25
25(0.669) = 16.7 units (answer)
When added, these two angles are supplementary, meaning that their sum is 180. This means that we can do the following to find x, and eventually DBC:
3x+67+4x+50=180
Simplifies to:
7x+117=180
Then by the Subtraction Prop. of Equality:
7x=63
Then divide by 7 on both sides to get that x=9.
We then substitute 9 into angle DBC.
4(9)+50
=36+50
DBC=86
:)
sub 2 for any "x"
3(2)^2-2(2)+1
6^2-4+1 i dont know if you need to simplify even more but if you do
36-4+1 32+1 31
i hope this helps you!
Hello,
y=4(x-2)²-1
y=4(x²-4x+4)-1
y=4x²-16x+15
