Answer:

z = 105°

Step-by-step explanation:

See attachment.

1.  The angle z plus 105° is equal to 180°, the straight line.  Z must therefore be = 105°

2.  Angles z and (15x + 45°) must be equal to 190°.

x is therefore equal to 4.

Solve the missing side. Find the missing side. Round to the nearest tenth. Please show the work. Part 2. #5-8​
enyata [817]

Answer:

5. 6.1 units

6. 29.4 units

7. 12.8 units

8. 29.1 units

Step-by-step explanation:

5. We have the opposite and adjacent sides here for angle 21 degrees. So we need to use tangent, which is opposite / adjacent:

tan(21)=x/16

x=16*tan(21) ≈ 6.1 units

6. We have the opposite and hypotenuse sides here for angle 33 degrees. So we need to use sine, which is opposite / hypotenuse:

sin(33)=16/x

x=16/sin(33) ≈ 29.4 units

7. We have the opposite and adjacent sides here for angle 37 degrees. So we need to use tangent, which is opposite / adjacent:

tan(37)=x/17

x=17*tan(37) ≈ 12.8 units

8. We have the opposite and hypotenuse sides here for angle 31 degrees. So we need to use sine, which is opposite / hypotenuse:

sin(31)=15/x

x=15/sin(31) ≈ 29.1 units

Hope this helps!

350kg of plastic is moulded to make garden pots weighing 1 whole 2/5 kg each. How many pots are made?​
slega [8]

The number of pots made are 250

The number of pots that can be made can be determined by dividing the total weight of the plastic by the weight of pots made

Number of pots made = Weight of plastic / weight of pot made

350 ÷ 1\frac{2}{5}

Convert the mixed fraction to an improper fraction

350 ÷ \frac{7}{5}

350 x \frac{5}{7} = 250 pots
