Answer:

By the Substitution property, the measure of angle ABC is equal to GHI.

Step-by-step explanation:

According to the Question,

Since we have,

  • Angle ABC and angle DEF are congruent ⇒ ∠ABC = ∠DEF-------(1 )  
  • Similarly,angle GHI and angle DEF are congruent ⇒ ∠GHI = ∠DEF------(2)

On substituting the value of from equation (1) to equation (2)

We get, ∠ABC = ∠GHI ∴ ∠ABC ≅ ∠GHI

Thus, By the Substitution property  

The measure of angle ABC is equal to angle GHI.

Answer:

1636 cm^2

Step-by-step explanation:

cut in itwo two shapes a rectangle and isosceles trapizoid

Area - 1/2 hight(base x length)

1/2 x 14(6x17) = 714 cm^2

Area of rectangle-  2(wl x hl x hw) = 922 cm^2

l = 17

w = 13

h = 8

add the areas - 922 + 714 = 1636 cm^2

The temperature, HH, in degrees Celsius, of a cup of coffee placed on the kitchen counter is given by H=f(t)H=f(t), where tt is
hjlf

Answer:

A) f'(t) is negative

B) degc/min

c ) At 20 minutes after the coffee was put on the counter its temperature is  56degc   and will decrease by about  1.125   in the next 45 seconds

Step-by-step explanation:

A ) f'(t)  is Negative because as the cup of coffee is placed on the counter there is loss of heat from the cup of coffee to the surrounding as t increases hence f'(t) is negative

B ) The units of  f'(20) = degc/min

C)  At ║f'(20)║ = 1.5 and f'(20) = 56

  ║f'(20)║ = 1.5 represents the rate of change of temp every 20 minutes = 1.5

  therefore after 45 seconds = 3/4 mins. change in temp = (3/4 * 1.5) = 1.125

At 20 minutes after the coffee was put on the counter its temperature is  56degc   and will decrease by about  1.125   in the next 45 seconds

XYZ is an isosceles triangle inscribed I a circle, center O. XY=XZ= 20 and YZ=18. Calculate to 3.s.f.
Vlad1618 [11]

Answer: 17.9

Step-by-step explanation:

Using Heron's formula:

Area of a triangle is given by:

√s(s-a)(s-b)(s-c)

Where a, b and c ara sides of the triangle and

S = (a+b+c) / 2

In the question above sides are :

XY=XZ= 20 and YZ=18

S = (20 + 20 + 18) / 2 = 58/2 = 29

Area = √29(29-20)(29-20)(29-18)

Area = √29(9)(9)(11)

Area = √25839

Area = 160.74513

Altitude = height(h)

Area = 0.5 × base × height

Base = yz = 18

160.74513 = 0.5 × 18 × h

160.74513 = 9 × h

h = 160.74513 / 9

h = 17.9 (3 s.f)
