Answer:
16 yards
Step-by-step explanation:
Using the formula
A=hb/2
Solving forb
b=2A/hb=2·72
9=16yd
6-y=4
6=4+y
2=y
The answer for Y would be 2
(-2.5,2) i would say is about the approximate
To look for it just look at the lines intersecting
Answer:
x = 50
Step-by-step explanation:
The sum of the interior angles of a quadrilateral = 360°
Therefore, add together the expressions for all 4 angles, equal to 360, and solve for x:
(2x + 15) + (3x - 20) + x + (x + 15) = 360
Gather like terms: 2x + 3x + x + x + 15 - 20 + 15 = 360
Combine like terms: 7x + 10 = 360
Subtract 10 from both sides: 7x = 350
Divide both sides by 7: x = 50
Their are two solutions.
X = -2/7 = 0.286
X = 1
