Write an expression used to find 4x275 using mental math and properties of numbers

1 answer:

5 0

What I suggest is to round the numbers. 4 rounds up to 5. 275 would round up to 280 or 300 whatever is easier. your expression would be 5*280 or 5*300.
I hope this helped :)

Find the value of unknown angle x,y,z,a,b,c with reasons and full process

Oduvanchick [21]

Answer:

Step-by-step explanation:

x = 70 degree (being vertically opposite angles)

y + 70 degree =180 degree (being linear pair)

y = 180 - 70

y = 110 degree

In triangle,

x + 60 + misssing angle = 180 degree (sum of interior angles of a triangle)

70 + 60 + missing angle =180

130 + missing angle = 180

missing angle = 180 - 130

missing angle = 50 degree

c = missing angle (being vertically opposite angles )

c = 50 degree

x + missing angle = a (sum of two interior opposite angles is equal to the exterior angle formed)

70 + 50 = a

120 degree = a

a = b (being vertically opposite angle

120 =b

therefore b is 120 degree

Hence , a = 120 degree , b = 120 degree , c = 50 degree , x = 70 degree , y = 110 degree
