Answer:
<h2>
x = 85° </h2>
Step-by-step explanation:
m∠ADC = 180° - 95° {a straight angle}
m∠ABC = 180° - x {a straight angle}
m∠ADC + m∠ABC = 180° {a quadrilateral inscribed in a circle}
180 - 95° + 180 - x = 180°
85° - x = 0
<u>x = 85° </u>
B+133=180
b=47
and 80+a+b=180
80+a+47=180
a=180-127
a=53
<h3>
Answer: 23.13 square meters</h3>
===============================================================
Explanation:
The top and bottom semicircles can be joined to form a full circle. The same can be said about the left and right semicircles. Each circle has diameter 3 and radius 1.5
The area of one circle is
A = pi*r^2
A = 3.14*(1.5)^2
A = 7.065
So two circles doubles to 2*7.065 = 14.13 square meters in area.
Then the last step is to add on the area of the 3 by 3 square (area 3*3 = 9) to get 14.13+9 = 23.13
This area is approximate because pi = 3.14 is approximate. Use more decimal digits in pi to get a more accurate area. However, your teacher wants you to use this specific value so it's best to stick with 23.13
-0.183 = -0.183 / 1
Numerator = -0.183 × 10 × 10 × 10 = -183
Denominator = 1 × 10 × 10 × 10 = 1000
Numerator / Denominator = -183 / 1000
Our simplified fraction is:
= -183/1000
