Here is a reference to the Inscribed Quadrilateral Conjecture it says that opposite angles of an inscribed quadrilateral are supplemental.
Explanation:
The conjecture, #angleA and angleC# allows us to write the following equation:
#angleA + angleC=180^@#
Substitute the equivalent expressions in terms of x:
#x+2+ x-2 = 180^@#
#2x = 180^@#
#x = 90^@#
From this we can compute the measures of all of the angles.
#angleA=92^@#
#angleB=100^@#
#angleC=88^@#
<span>#angleD= 80^@#</span>
Answer:
z=9/2
Step-by-step explanation:
36-8z=0
36=8z
z=36/8
z=9/2
Answer:
Well the original price would be $44
Step-by-step explanation:
So make an equation
Lets make X stand for the price before the deduction
so x-x(0.3)=30.80
Subtracting the X by x(0.3) would tell us the price, the 0.3 stands for 30 percent and we know its 30 percent of X so we subtract that since 0.3x would give the change
Now just solve the equation
You’ll get 44.
Answer:
12
Step-by-step explanation:
Distrubute (y +2 = -3x + 12)
subtract 2 on both sides ( y +2 = -3x + 12 )
-2 -2
conbine like terms (y = -3x + 10)
Answer:
Ou seja, nesse caso, 15 reais para cada uma, escrevendo de uma maneira mais simples:
" 15 para as duas"
E assim obtemos a resposta, a letra b) 1:45, pois são 15 para as duas.
Step-by-step explanation:
