Answer:
Step-by-step explanation:
5. The opposite angles of a cyclic quadrilateral sum to 180 so
9y + 5 + 18x + 4 = 180 and
9y - 9 + 21x + 6 = 180
Solve this system to find x and y.
7. Solved in the same way.
Have to go right now so i cant help you any further.
3t - 15 = 2t + 10
t = 25
<Y = 2(25) + 10 = 60
<X = 4r
so
4r + 60 = 180
4r = 120 (<X = 4r)
answer
<X = 120
Answer:
so many bots have replied to my questions :\\\
Step-by-step explanation:
It would depend on if the triangle was regular or irregular.So no if the triangle has different angles.If that is so then...
False.
12 x 6 x 3 =216. He can dress himself up in 216 different ways.
I hope this helps!
