Answer: 14.86 yards
Step-by-step explanation:
A landscaper is designing a flower garden in the shape of a trapezoid. She wants the shorter base to be 3 yards greater than the height and the longer base to be 7 yards greater than the height. She wants the area to be 295 square yards. The situation is modeled by the equation …
For this case we must solve the following linear equation:
Adding to both sides of the equation we have:
Subtracting 17 from both sides of the equation:
Different signs are subtracted and the major sign is placed:
We divide by 14 on both sides of the equation:
Answer:
Complementary angles are angles whose sum are equal to 90
degree. So
Let x be the one angle
And y be the second angle
X +y = 90
X – y = 90 -72 = 18
Adding the two equation
2x = 108
X = 54
Y = 90 -54 = 36 degrees is the smaller angle
120 the formula for interior angles of a shape is ((n-2)180)n
