so 56.52 is not correct
Answer:
C
Step-by-step explanation:
x+4y=-12
x+7y=-15
subtract
-3y=3
y=-1
x+4(-1)=-12
x=-12+4=-8
so point is (-8,-1)
Answer:
B
Step-by-step explanation:
since it hints that it is less than we can see that B gives it to us also it can't be A cuz 42 is greater than 36
so it is B

Answer:
A. 90°+m∠4
Step-by-step explanation:
Also
∠
A

∠
C

180 o
=
∠
B

∠
D
⇒
2
x+
(
3
x
−
5
)
=
180 0
=
(
x
+
5
)
+ ∠ C
5
x − 5 = 180
Add 5 to both sides
5
x = 185
Divide both sides by 5
x = 185 5 = 37
But it was A. 90°+m∠4
