Answer:
it is isosceles triangle with an angle = 90. Two others angle are equal. sum of all angles in triangle is 180.
2x + 90=180 --> x=45
Convert to Y=MX+B to make it easier, minus 2x from both sides to get -7y=-2x+14, then divide it all by -7 to get y=2/7x-2. 2 equals your starting point, from there go down 2 and over 7 for you slope and repeat until the graph is done.
Answer:
see explanation
Step-by-step explanation:
Using sum to product identities
cos x - cos y = - 2sin(
)sin(
) = 2sin( )sin(
)
cos x + cos y = 2cos( )cos( )
Note that
sin10° = sin(90 - 10)° = cos80°
Thus
← cancel 2 from numerator/ denominator
= 
× 
= tan45° × tan35° { tan45° = 1 ]
= 1 × tan35°
= tan35° ← as required
<span>The rocket that will reach a greater distance above the ground at its maximum height is y = -4x</span>² + 80x. The answer is letter B. This is because of the coefficient presented in the x² term. The number -4 is much greater than -6. Graphing these equations into a graphing paper or excel, you would get a parabola.
