Do 4x9+5 because you multiply 4 and c and then add on d.
3.14 - 3a Radians
Because
180o = 3.14 radian
Tan(a/2) = sin a / (1 + cos a)
tan(45/2) = sin(45) / (1 + cos(45)) = (1/√2) / (1 + 1/√2) = (1/√2) / (√2 + 1)/√2 = 1/(√2 + 1) = (√2 - 1)
Answer:
x=13
Step-by-step explanation:
119-2=117
117÷9=13
9×13+2=119
