2x+4y=22
2x+2y=15
Answer:
x = 4
y =
Step-by-step explanation:
Ummmm
I'm not sure if this is corrrect but this is what I got
So first you solve 2x+4y=22 to find x
and you get x =
Then you have to subtitute for in
which you then get y=
After you have to subttitute y= for y in x =
which you get as x=4
Finally you get the answer as:
x = 4
y =
Answer:
option H, 130°
Step-by-step explanation:
In order to find the measure of ∠ACD, first find the measure of ∠ACB
∠ACB + ∠ABC + ∠BAC = 180° (angle sum property of a triangle)
∠ACB + 95° + 35° = 180°
∠ACB + 130° = 180°
∠ACB = 180° - 130°
∠ACB = 50°
∠ACD + ∠ACB = 180° (linear pair)
∠ACD + 50° = 180°
∠ACD = 180° - 50°
∠ACD = 130°
therefore, option H is the correct option
hope it helps you!
