Answer:
D. tan <em>0</em><em> </em>= 8/15 and A. sec <em>0</em><em> </em>= 17/15
Step-by-step explanation:
Cos <em>0</em> = adjacent/ hypotenus
Adj = 15 and Hyp =17
Using pythagoras theory
Opp^2 = 17^2 - 15^2
Opp^2 = 289 - 225
Opp^2 = 64
Therefore <em>Opp</em><em> </em><em>=</em><em> </em><em>8</em><em> </em><em>which</em><em> </em><em>is</em><em> </em><em>the</em><em> </em><em>square</em><em> </em><em>root</em><em> </em><em>of</em><em> </em><em>6</em><em>4</em>
tan <em>0</em><em> </em>= opp/adj
tan <em>0</em><em> </em><em>=</em><em> </em>8/15
Sec <em>0</em><em> </em>is the multiplicative inverse of cos <em>0</em>
Answer:
B. 9
Step-by-step explanation:
3^4/3^2
lets expand it
3 * 3 * 3 * 3/ 3 * 3
just get rid the 3's needed to get rid of the denominator which is 2, so get rid of 2 threes from the top
3 * 3 = 9
And it's okay, I dislike math too. Hope you feel better.
I’m pretty sure that its A. because B. doesn’t mention 8 like A does
Its A.
It is a square has 4 equal sides and a pentagon has 5 so the answer is
SQUARE
Y = 0.8
4x + 8y = 40
4x + 8*(0.8) = 40
4x + 6.4 = 40
4x = 40 - 6.4
4x = 33.6
x = 8.4
