There are alike because if you switch the order of the number it equals the same
Answer:
A = 1/2bh
b = 2cm
h will be found using the side of the triangle with Pythagoras theorem
h² + 1² = 4²
h² = 15
h = √15 cm
then,
A = <u>2</u><u>*</u><u>√</u><u>1</u><u>5</u><u> </u>
2
A = √15cm²
The next number would be 63
Answer:
A. 1/2
Step-by-step explanation:
20x=10
Divide 20 on both sides of the equation to get x by itself
20x=10
___. __
20. 20
x =1/2
Answer:
40° and 140°
Step-by-step explanation:
A linear pair of angles sum to 180°
let x be one angle then the other is 3.5x and summing gives
x + 3.5x = 180
4.5x = 180 ( divide both sides by 4.5 )
x = 40
one angle = 40° , the other is 3.5 × 40° = 140°
