Answer:
x = 70°
Step-by-step explanation:
Itz given that AB & CD are perpendicular to each other and intersect at E . So , angle(AED) = 90°
But here the value of angle(AED) = 90°
So,
x + 20 = 90°
=> x = 90° - 20°
= 70°
Answer:
To represent parts of whole numbers, we use fractions.
So if 4 kids are sharing 3 cookies, what happens?
First, we divide one cookie into four equal parts, and give one part to each kid. Then we do the same with the second cookie, and then with the third one.
In the end, each kid will have three pieces. Each piece is a whole cookie divided into four equal parts.
So we represent this amount as
3 (Number of parts) & 4 (How many equal parts the whole is divided into)
3
4

A fraction is made of two numbers :
1/4 mile per minute is the average speed.
Rotational symmetry. Because you can rotate it and put a line through it and it would all look the same
