SinA = 3/5
cosA = 4/5
cosB = 3/5
sinB = 4/5
sin(A+B) = sinAcosB + cosAsinB
= (3/5)(3/5) + (4/5)(4/5)
= 9/25 + 16/25
=(9+16)/25
=25/25
=1
therefore, the answer is B
First one C second one D sorry if I’m wrong
Y=0 or the horizontal line could be described as undefined since it had no slope
Answer: C. 47 degrees
Step-by-step explanation:
85+48=133
All triangles interior angles are equal to 180
180-133=x
180-133=47
The answer is 6
First, you must put the values in the formula.
Then, you must simplify the exponents.
Next, subtract 64 on both sides.
Finally, eliminate exponents.
