It’s the sixth one good luck stay safe and thank you if you give me brainliest
Answer: x=27
Step-by-step explanation:
3x-4(4)=65
3x-16=65
3x=65+16
3x=81
3x/3=81/3
X=27
3 x^{2} - 15x - 42
(x-7)(x+2)
x-7=0 x+2=0
x=7,-2
Answer:
13200n: 4 is 600
Step-by-step explanation:
Answer: 32.23°
Suppose the setpoint of a helicopter is A and that of a car is C and that of the road is B
The distance from the helicopter to the car and the road forms a right triangle
=> ΔABC is a right triangle at B
=> the angle of depression from the helicopter from the car is ∠ACB
we have: ΔABC is a right triangle => sin ∠ACB = 24/45
=> m∠ACB = 32.23°
