Find each unknown angle measurement.

Mathematics
1 answer:
Alex Ar [27]2 years ago
5 0

Answer:

angle(2) = 118 degree

angle(3) = 118 degree

angle(4) = 62 degree

Step-by-step explanation:

To find angle 2 :

62   + angle{2} = 180 \\ angle{2} = 180 - 62 = 118 \: degree

The rule (head to head):

angle(2) = angle(3) = 118 degree

And the last one is angle(4) which is the same thing:

angle(4) = angle(1) = 62 degree

Find the area of the composite shape
Alexxandr [17]

Answer:

13.735 ft^{2}

Step-by-step explanation:

Area of a circle.

A=\pi r^{2}

r=d/2\\r=8/2\\r=4

A=\pi \times 4^{2}

A=16\pi

A \approx 50.2654824574

Area of a square.

A=s^{2}

A=8^{2}

A=64

Subtract the area of the square with the area of the circle.

64-50.2654824574

= 13.7345175426

I hope it helps.

Brainliest much appreciated.

THE NUMBER 1-10 ARE IN A BAG, YOU TAKE 2 OUT WITHOUT REPLACEMENT. WHAT IS THE PROBABILITY OF DRAWING THE NUMBER 7 THE FIRST TIME
ehidna [41]

Answer:

1 / 18

Step-by-step explanation:

PROBABILITY OF DRAWING THE NUMBER 7 THE FIRST TIME = Number of favorable outcome / Total number of outcomes

Favorable outcome = 1

Total number of outcome (1,2,3,4,5,6,7,8,9,10) = 10

PROBABILITY OF DRAWING THE NUMBER 7 THE FIRST TIME  = 1 / 10

PROBABILITY OF DRAWING AN EVEN NUMBER THE SECOND TIME = Number of favorable outcome / Total number of outcomes

Favorable outcome (2,4,6,8,10) = 5

Total number of outcomes (1,2,3,4,5,6,8,9,10) = 9

PROBABILITY OF DRAWING AN EVEN NUMBER THE SECOND TIME = 5/9

PROBABILITY OF DRAWING THE NUMBER 7 THE FIRST TIME AND THEN DRAWING AN EVEN NUMBER = 1 / 10  * 5 / 9 = 1 / 18
