Answer:
angle c = <u>83</u> degrees
Step-by-step explanation:
Opposite angles of an inscribed quadrilateral add up to 180 degrees.
According to the rule, <D and <B add up to 180° and same for <A and C.
This means that the sum of (x + 100) and (3x) equal 180.
Therefore (x + 100) + (3x) = 180 →
4x + 100 = 180
–100 –100
4x = 80
÷4 ÷4
x = 20.
Since x = 20, <A = 5x – 3 = 5(20) – 3 = 97.
Since <A + <C = 180.
97 + <C = 180 → 97 + <C = 180
–97 –97
<C = 180 – 97 = 83°
Four and two thirds multiplied by two is:
4*2=8
2/3 * 2 = 4/3 or one and one third
so the answer to your question is:
9 1/3
Answer:
Where are the radical expressions?
Step-by-step explanation:
Answer:
312
Step-by-step explanation:
First we need to determine the width
A = l*w
6.2 * 10 ^3 = 1.55 * 10 ^2 * w
Divide each side by 1.55 * 10 ^2
6.2 ^ 10 ^3 /1.55 * 10 ^2 = 1.55 * 10 ^2 * w / 1.55 * 10 ^2
Changing from scientific notation to standard
6200/155 = w
40 = w
Then we need to determine the perimeter
P = 2(l+w)
P = 2( 155+40)
P =2( 195)
P = 390
Now multiply by the price
390 *.80
312
