Two parts there: 14 the integer and 14/20, a fraction which needs to be converted to decimal.
14/20 = 7/10=0.7
combining, the ans is 14.7

a=-11
b=-9
Answer:
13.08
Step-by-step explanation:
First find the area of the circle
A = pi r^2
A = 3.14 * 5^2
A =3.14 *25
A =78.5
The angle of the purple sector is 60 degrees
A full circle is 360 degrees
The fraction of the circle that is purple is 60/360 = 1/6
Multiply the area of the circle by 1/6
1/6* 78.5 =13.0833333
Rounding to the nearest hundredth
13.08
We know that
in a right triangle
if sin A= cos B
then
angle A and angle B are complementary angles
so A+B=90
therefore
(2x-8)+(6x-6)=90-------> 8x-14=90----> 8x=104--------> x=13°
(2x-8)-----> 2*13-8----> 18°
(6x-6)-----> 6*13-6----> 72°
<span>if α < β
</span>then
<span> α =18</span>°
<span> β=72</span>°
