Answer:
1) b = 60°
2) a = 90°, b = 90°
Step-by-step explanation:
1) Angles on a straight line add to 180° so 180 - 120 is 60°
2) The two lines are perpendicular (meet at right angles) so both angles are 90°
Hope this helps!
Answer:
m=0.55
Step-by-step explanation:
Divide each term by 13 and simplify.
length =88cm
breadth=21cm
when it is rolled it becomes cylinder
having circumference 88cm
2πr=88cm
r=88×7/44
r=14
h=21
total surface area of the cylinder =2πr(r+h).
=2×22/7×14(14+21)
=3080cm²
The ratio is 4:7 because since the ratio is red apples to green apples theirs 4 red apples and theirs 7 green
