(a) a = 10.9 cm
(b) b = 20.78 cm
(c) c = 4.06 cm
<u>Explanation:</u>
(a)
height, h = 5cm
Hypotenuse, H = 12cm
Base, a = ?
Using pythagoras theorm:
(H)² = (h)² + (a)²
(12)² = (5)² + (a)²
119 = a²
a = 10.9 cm
(b)
Hypotenuse, H = 24 cm
Base, a = 12 cm
Height, b = ?
Using pythagoras theorm:
(H)² = (b)² + (a)²
(24)² = (b)² + (12)²
432 = b²
b = 20.78 cm
(c)
height, h = 4 cm
Hypotenuse, H = 5.7 cm
Base, c = ?
Using pythagoras theorm:
(H)² = (h)² + (c)²
(5.7)² = (4)² + (c)²
16.49 = c²
c = 4.06 cm
Answer:
y = negative 2 x + 9
Step-by-step explanation:
It would be 8.5 because all you have to do is add 3 to 2.5 then you’ll get 5.5 then do that one more time.
Here to solve the equation we need to plug in the value y as given. -5x+2(7x)=9. -5x+14x=9. 9x=9. X=1.
