The length of a rectangular mural is 2 ft more than three times the height. The area is 165 ft^2. Find the height of the mural.

Mathematics
1 answer:
NISA [10]4 years ago
5 0

Answer:

x=-1±4√31/3 ft is the height

Step-by-step explanation:

let the height be x ft.

then the length would be 3x+2

area = L*H= x(3x+2)

165=3x²+2x

0= 3x²+2x -165

dividing the whole equation by 3

0=x²+2x/3-55

(x)²+2(x)(1/3) +(1/3)² -55 -(1/9)=0

(x+1/3)²- 495-1/9=0

(x+1/3)²= 496/9

taking square root on both sides

(x+1/3)= ±4√31/3

x= ±4√31/3-1/3

x=-1±4√31/3 ft is the height

Which statement justifies why ∠EBC measures 90°?<br><br> Given: angles ABD and DBC are complementary
luda_lava [24]

The statement that justifies why ∠EBC measures 90° is that the  sum of the measures of two complementary angles is 90 degrees.

<h3>What are  complementary angles?</h3>

The  complementary angles are angles that when we find their  sum  it will be  equal to 90 degrees and that is why its been regarded as the  complementary angles.

We can see that m∠ABD and m∠DBC are complementary, because m∠ABD + m∠DBC=90°

Therefore, The statement that justifies why ∠EBC measures 90° is that the  sum of the measures of two complementary angles is 90 degrees.
