<h2>54 units²</h2><h2 />

This is a compound shape. You can split it into x shapes. See Attachment

  • Rectangle - Red

Area of a Rectangle = L × B

L = 7

B = 6

7 × 6 = 42

<h3>42 units²</h3>

  • Triangle - Orange

Area of a Triangle = 1/2BH

B = 6

H = 1

1/2 × 6 × 1 = 3

<h3>3 units²</h3>
  • Triangle - Green

Area of a Triangle = 1/2BH

B = 3

H = 2

1/2 × 3 × 2 = 3

<h3>3 units²</h3>

  • Triangle - Blue

Area of a Triangle = 1/2BH

B = 2

H = 6

1/2 × 2 × 6 = 6

<h3>6 units²</h3><h3 /><h3>42 + 6 + 3 + 3 = 54</h3>

a ferry shuttles people from one side of a river to the other. the speed of the ferry is still water is 25 mi/h. the river flows
Anarel [89]

Answer:

The Terry's resultant speed is 27mi/h

Direction of ferry=20°

Step-by-step explanation:

(-25,0) + ( 0, 9)= (-25, -9) is the vector representing the movement of the ferry

Speed of ferry = sqrt[(-25)^2 + (-9)^2]

Speed= sqrt (-625 + (-81))

Speed= sqrt(-706)

Speed=26.57mi/h

Nearest tenth,speed= 27mi/h

Tanz° = (-9/-25)

Tanz°= 0.36

Z°= tan^-1 0.36

Z= 19.80°

Nearest tenth,z=20°

Please help me i have no clue what the answer is :?
Nadusha1986 [10]

Answer:

1. Yes

2. They could change the 60° angle into a different one.

Step-by-step explanation:

1. Two triangles are the same if they share two side lengths with the same angle between them.

2. Since the triangles are equal if they share two side lengths with the same angle between them, if they changed the angle between 3 and 5, it'd no longer be the same triangle.

Given 3 sides of a triangle - how to tell it right, acute, or obtuse 8,11, 16
user100 [1]
Using Pythagorean theorem, we can justify our answer.
if c^2 = a^2 + b^2 then triangle is right one,
if c^2 > a^2 + b^2 then triangle is obtuse and
if c^2 < a^2 + b^2 then triangle is acute triangle.

Here a=8, b=11 and c=16
Put these values in the equation
16^2 = 8 ^2 + 11^2
256 = 64 +121
256> 185
So here c^2 > a^2 + b^2  Which means triangle is obtuse triangle.

Answer: Obtuse Triangle
