Answer:
<h3>m∠1 = 49°</h3><h3>m∠2 = 63°</h3><h3>m∠3 = 87°</h3><h3>m∠4 = 44°</h3>
Step-by-step explanation:
m∠1 = 49° (Opposite Angles)
m∠1 + m∠2 + 68° = 180° (The sum of all interior angles of any triangle is equal to 180°)
49° + m∠2 + 68° = 180°
m∠2 + 117° = 180°
m∠2 = 180° - 117°
<u>m∠2 = 63°</u>
m∠3 + 93° = 180° (The angles on a straight line add up to 180°)
m∠3 = 180° - 93°
<u>m∠3 = 87°</u>
m∠4 + 49° = 93° (An exterior angle of a triangle is equal to the sum of its two interior opposite angles.)
m∠4 = 93° - 49°
<u>m∠4 = 44°</u>

The answer has no solution because it is infinite and that's your vairiable
Answer:
104.8cm³(1 decimal place)
Step-by-step explanation:
Volume of a cone is given by the formula
V=1/3πr²h
we are given a radius of 5 and a height of 4 so we will just substitute for the values and we will give our pie as 22/7
V=1/3× 22/7×5²×4
V=1/3 × 22/7 ×25 ×4
V=2200/21
V=104.76190476
V=104.8cm³(1decimal place)

Total time = upstream time + downstream time
he rowed the same distance both ways.
upstream time = D/4
downstream time = D/6
total time = D/4 + D/6 = 3D/12 + 2D/12 = 5D/12 = 3 hours
D = 3*12/5 = 36/5 or 7.2 miles
where D is the one-way distance. The total distance he rowed is 2*D = 72/5 or 14.4 miles
