Answer:
AC = 3.72 units
Angles:
A = 132.6°
C = 27.4°
Step-by-step explanation:
AC² = 5² + 8² - 2(5)(8)cos(20)
AC² = 13.82459034
AC = 3.718143399
3.718143399/sin20 = 8/sinA
sinA = 0.7358944647
A = 180 - 47.38285134
A = 132.6171487
3.718143399/sin20 = 5/sinC
sinC = 0.4599340405
C = 27.38285134
11 because -7 subtracted by 4 add kore to the 7 so think of it this way -7 is a bad guy and 4 is a bad guy to because its a subtraction so if both bad guys combine you get 11 because a negative with negative makes a positive so its 11
Answer:
Step-by-step explanation:
That composite figure is made up of a square and a quarter of a circle. We will first find the area of the square. Then we will find the area of the circle and divide it by 4.
Area of square = 1.6 × 1.6
Area of square = 2.56 m squared
Area of circle = (3.14)(1.6²) In case you forgot, the area of a circle is A = πr².
Area of circle = 8.0384
Divide that by 4 to get 2.0096.
Add 2.0096 to 2.56 to get the total area, which is
4.5696 or 4.6 rounded (choice D)
Even tho you did me dirty i will answer you.
You can subtract the whole number
