Answer:
A = 60.07°
Step-by-step explanation:
Sin A = 
Sin A = 
Sin A = 0.867
A = Sin⁻¹ 0.867
A = 60.07°
Answer:
x=3+3/4
Step-by-step explanation:
1+4x/6=3.5
We move all terms to the left:
1+4x/6-(3.5)=0
We add all the numbers together, and all the variables
4x/6-2.5=0
We multiply all the terms by the denominator
4x-(2.5)*6=0
We add all the numbers together, and all the variables
4x-15=0
We move all terms containing x to the left, all other terms to the right
4x=15
x=15/4
x=3+3/4
Its the first one because -3(-2)=6, 1(-2)=-2, 2(-2)=4 are all correct
