10 and -4. You multiply 10 times -4 to get -40 and you add 10 and -4 to get 6
Answer:
<u><em>Answer is below</em></u>
Step-by-step explanation:
Answer:
25) 3 = 5 + secΘ where we have 2 possible values of Θ (2π/3 or 4π/3)
<em>3 = 5 + sec (2π/3)</em>
<em>3 = 5 + sec (120 degrees)</em>
<em>3 = 5 + (-2)</em>
<em>3 = 3</em>
theta = 4π/3
<em>3 = 5 + sec (240 degrees)</em>
<em>3 = 5 + (-2)</em>
<em>3 = 3</em>
Therefore, the equation is true for both 2π/3 and 4π/3
27) -2 SinΘ = -1 {π/6 , 5π/6}
<em>-2 * sin(π/6) = -1 </em>
<em>sin(π/6) = 1/2</em>
1/2 = 1/2
LHS = RHS
theta = 5π/6
<em>-2 sin(5π/6) = -1 </em>
<em>sin(5π/6) = 1/2 </em>
1/2 = 1/2
LHS = RHS

Answer:
Y= 30
Step-by-step explanation:
180-70=110 So now you know what your other two angles add up to.
Take 110 and your two other problems (3y-20) and (y+10)
Substitute y for a random number, as in 30.
Do the math (3(30)-20)
90-20=70 [Now your previous 110 is 40}
Then for the second equation (30+10)= 40
Y=30
