Is this good led me know pl<br> Give GHJ=XJZ find each missing measure
lbvjy [14]

Answer/Step-by-step explanation:

Given that ∆GHJ is congruent to ∆XYZ, this:

<G = <X,

<H = <Y = 38°

<J = <Z,

GH = XY = 27 ft

HJ = YZ = 27 ft (two sides of an isosceles ∆ are the same)

GJ = XZ = 18 ft

a. GJ = 18 ft

b. XY = 27 ft

c. ZY = 27 ft

d. m<H = m<Y (corresponding angles)

m<H = 38° (substitution)

e. m<Z = (180 - 38)/2 (base triangles of an isosceles ∆ are equal)

m<Z = 142/2

m<Z = 71°

f. m<J = m<Z (corresponding angles)

m<J = 71° (substitution)

A box of facial tissue has a volume of 180 cubic inches. What is the width of the box if the height was 4 inches, and the length
algol13

Answer:

The width of the box is 5 in

Step-by-step explanation:

the formula for the volume of a rectangular box of length L, width W and height H is V = L*W*H.  Here we know V, L and H and want to find W.  Solving this equation for W, we get W = V/(LH).

With V = 180 in^3, H = 4 in and L = 9 in, W comes out to be

            180 in^3

  W = ------------------ = 5 in

            (4 in)(9 in)

The width of the box is 5 in

lions [1.4K]

Answer:

21785.1548486

Step-by-step explanation:

The growth rate is expressed by,

m'(t)=27te^{3t}

when t=2days,

m'(2)=27*2e^{3*2}

m'(2)=27*2e^{3*2}

      = 54*e^{6}

      = 21785.1548486
