As the complete angle is right angle that is 90°
So both the angles should add up to 90°
(3x+2) + (x+16)=90
combine the like terms
4x+18 = 90
Subtract 18 from both sides
4x= 72
divide both sides by 4
x=18
Answer:
(i) The value of<em> m</em> when t = 30 is 13.2
(ii) The value of <em>t</em> when the mass is half of its value at t=0 is 34.7
(iii) The rate of the mass when t=50 is -0.18
Step-by-step explanation:
(i) The <em>m</em> value when t = 30 is:

Then, the value of<em> m</em> when t = 30 is 13.2
(ii) The value of the mass when t=0 is:
Now, the value of <em>t </em>is:


Hence, the value of <em>t</em> when the mass is half of its value at t=0 is 34.7
(iii) Finally, the rate at which the mass is decreasing when t=50 is:

Therefore, the rate of the mass when t=50 is -0.18.
