If the sin(3x + 10)º = cos(x + 24)º, find x.
a) x = 10
b) x = 14
c) x = 20
d) x = 28

B) x=14

Step-by-step explanation:

Since sine and cosine are equal, the angles must be complementary.

3x + 10 + x + 24 = 90

4x + 34 = 90

4x = 56

x = 14

your welcome and everyone is smart some just dont know one of the answers

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.
