Answer:
I think it would be A
Step-by-step explanation:
The answer is 135 degrees as 45 add 135 equals 180 degrees as it's a straight line
Answer:
height is 15
Y = L = Length
therefore 15y = (-x^2) +(300/20)
Step-by-step explanation:
15 = -x^2 +(300/20)
is the same as;
15 = (300/20) - (x^2)
we just add y to 15 and that can represent a division for x
y = L
Where area cm^2 can be shown as 300 as 15 x 20 = 300
when we divide by length we get the height as asked in the question.
Answer:
x = 114°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles, thus
x + 18° = 132° ( subtract 18° from both sides )
x = 114°
