The discriminant of a quadratic equation is calculated through the equation,
D = b² - 4ac
In the given above, a = 5, b = -4, and c = 3. Substituting these values to the equation,
D = (-4)² - 4(5)(3) = -44
Since the discriminant is negative, the roots are non-real.
You multply 4.5cm x 5 cm then divide it by 2 to get triangle then multply 4.5 x 4.5 to get the square in the middle
Answer:
Multiply 54 and 6
Step-by-step explanation:
Answer:
45°
Step-by-step explanation:
The angles of any triangle add up to 180 degrees
add the two known angles: 47+88=135
then subtract the sum from 180 to get answer: 180-135=45
