First, find the arc measure BD. The arc measure is twice the central angle measure. BD should be 48*2 = 96.
The chord BC looks like it’s the diameter of the circle, so it must have a measure of 180.
From here you can find DC. The total measure of a circle is 360.
360- 96-180 = 84, so DC is 84.
DBC is 360- DC
so 360- 84 = 276.
DCB is just 360- BD
so 360- 96 = 264.
Hope this helps!
Answer:
16 and 82 degrees
Step-by-step explanation:
You can sum all of the angles together and solve for x.
(x - 1) + (5x - 3) + (5x - 3) = 180
11x - 7 = 180
11x = 187
x = 17
The first angle is 16 degrees. (17 - 1)
The other two angles are 82 degrees(5(17) - 3)
Answer:
4 4/9
Step-by-step explanation:
First, you have to set it up: 5/9 times 8/1
We made it 8/1 since it has to be a fraction in the multipying ocess and the one does not change the value.
Next, Multiply.
5/9x8/1=40/9 as an inproper fraction
As a proper fraction, it is written as 4 4/9
B)257.1
Explanation: Area of a square : length x width
Area of square = 12x12= 144
Area of a circle: pie(radius)^2
diameter:12
radius:12/2=6
Area of a circle: pie(6)^2=113.1
ADD BOTH AREAS
Area of the figure =144+113.1
=257.1
