Answer:
90°-x°=180°[by linear pair]
x=180°-90°
x=90°
angle cbd=45°
45°- (x+5)°=90°
x+5=90-45
x+5=45
x=45-5
x=40
angle abc
x+5
40+5
45°
Answer:
103°
Step-by-step explanation:
Let's take the 3rd angle as θ:
Since all the angles in a triangle add up to 180°,
57 + 20 + θ = 180
77 + θ = 180
θ = 180 - 77
= 103°
Hence, the third angle is 103°

Answer:
One bottle of soap will hold 3/8
Step-by-step explanation:
3/4= The amount of soap she has in total
3/4= 6/8 which is the same amount but now we can divide it by 2
.75 (6/8) divided by 2= .375 (3/8)
So each soap dispenser will have 3.75 liters of soap.
Sentences: To check our work
.375x2= .75
3/4 divided by 2= 3.75
Answer:
r = 4.9 km
Step-by-step explanation:
Perimeter of circle = πr
Where P=15.42 km , π = 3.14
15.42 = (3.14)(r)
r = 15.42 / 3.14
r = 4.9 km
