The answer to your question will be C
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°
Standard form,written from,and expanded form
Ok i can’t write all of these but just use Microsoft calculator it helps a lot i always use it good luck !!
The initial amount is 100%. you want to decrease it by 85%:
The decreased amount will be 100% - 85 % = 15%
If te amount was "x" and you wand to decreased by 85%, then
you multiply x.15% = 15%.x
