Answer:
a = 3
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
a² + 8² = ( )²
a² + 64 = 73 ( subtract 64 from both sides )
a² = 9 ( take the square root of both sides )
a = = 3
Answer:
no Y dose not vary directly with X
aka (A)
Step-by-step explanation:
70 degrees
Angle FED = 180 - 140 = 40
180 (sum of all angles in a triangle) - 40 = 140
140/2 = 70
Answer:
(i) 4*8 = 32
(ii) 2* (4 * 8) = 64
Step-by-step explanation:
(i) 4*8
4 × 8 = 32
(ii) 2* (4 * 8)
2 × (4 × 8)
2 × (32)
2 × 32 = 64
