Not good, at all man, you should really invest in a tutor.
Answer:
8
Step-by-step explanation:
The 30-60-90 triangle rule states that the hypotenuse is equal to the short leg times 2. So 4 x 2 = 8.
Answer: the solutions are
x = 3 or x = - 11
Step-by-step explanation:
The given quadratic equation is expressed as
y = 2x² + 16x - 66 = 0
The equation is already in the standard form of ax² + bx + c
The general formula for solving quadratic equations is expressed as
x = [- b ± √(b² - 4ac)]/2a
From the equation given,
a = 2
b = 16
c = - 66
Therefore,
x = [- 16 ± √(16² - 4 × 2 × - 66)]/2 × 2
x = [- 16 ± √(256 + 528)]/4
x = [- 16 ± √784]/4
x = (- 16 + 28)/4 or x = (- 16 - 28)/4
x = 12/4 or x = - 44/4
x = 3 or x = - 11
G1 = -7 , g2 =5 I think this is it
If its a right-angled triangle you can find the third side if the length of the other 2 sides are known. Use the Pythagoras theorem.
If you have 2 triangles which are similar and you know the length of one or more sides of one of them then you can find the lengths of corresponding sides in the second triangle.
