180 - 30 = 150or triangle is isoscele so each base angle is 150 / 2 = 75
Answer:
First one
Step-by-step explanation:
(x - h)² = 4p(y - k)
(h,k) = (-5,2)
p = 2 - -1 = 3
(x - -5)² = 4(3)(y - 2)
(x + 5)² = 12(y - 2)
y - 2 = (1/12)(x + 5)²
The answer is 2/7 or 0.28571428... You can find this the same way as your other problem by finding the common denominator and multiplying. (Also, if you go on Mathway, you can find solutions to almost any problem really quickly.)
Hope this helps!

Answer:
100 yards
346.6 yards
There are two constants, across the level of competition: 120 yards (360 feet) of length and 53 1/3 yards (160 feet) of width. The playing field is 100 yards long, with a 10-yard-deep end zone on each side. In total, a football field covers 57,600 square feet, or the equivalent of 1.32 acres.
Answer: The equation that describes proportional relationship is y = 0.75x
Constant of proportionality is 0.75
Step-by-step explanation:
4y = 3x
Divide both sides by 4 to get the value of y
y = 3x/4
12y = 9x
Divide both sides by 12 to get the value of y
y = 9x/12 divide the numerator and denominator by a common value of 3
y= 3x/4
y = 0.75x
The equation that describes proportional relationship is y = 0.75x, meaning y is inversely proportional to x, as x increases, y also increases.
Constant of proportionality is 0.75
