Find the measure of the angle indicated

Mathematics
1 answer:
Bond [772]3 years ago
3 0

Answer:

76°

Step-by-step explanation:

The sum of two interior angles in a triangle is equal to an exterior angle that's supplementary to the third interior angle

52° + 12x + 4 = 22x - 4

52 = 22x - 4 - 12x - 4

52 = 10x - 8 add 8 to both sides

60 = 10x divide both sides by 10

6 = x

The measure of angle F is 12x + 4, replace x with the value we found

m<F 12 × 6 + 4 = 76°

What is the volume of a cylindrical bucket that is 35 cm tall and has a base with a diameter of 21 cm? Use pi= 22/7 and round yo
Natali [406]
The volume of a cylinder is given by the multiplication of the area of the base by the height of the cylinder.  π×r²(area of the base) × h (height of the cylinder) ⇔
\frac{22}{7}×(\frac{21}{2} )^{2}cm²×35cm=12127.5cm³
(r is half of the diameter. Because we are doing the square of r, the cm also are squared.)
Rounding to the nearest tenth is to round the result so that it maintains a number after the point - the result is 12127.5cm³
