Only two triangles:
The 90* angle is stable, so you can change only the position of the 50* and 40* angles.
1 triangle: 40* is right to the 90*
2 triangle: 40* is left to the 90*
Hope this helped you!
Answer:
idk cause you didnt give us any choices lol
Step-by-step explanation:
Answer:
Relation 3 is not a function, as s has two outputs: tree and desk. Relation 4 is not a function for the same reason. -1 has three outputs: -2, -4, and -7.
I assume what you want ti find is the value of m?
You try to have an quation of the form "m=" where on the one side there is nothing but m.
so first, let's get rid of the bracket:
-2(4-m)=10
-8+2m=10
now, let's add 8 to both sides:
-8+8+2m=10+8
2m=18
and divide by 2:
m=9
and that's our solution
∠RSV=(3x + 7)°
∠RST = (8x − 12)°
∠RSV=∠VST=1/2∠RST
(3x + 7)°+(3x + 7)°= (8x − 12)°
3x+7+3x+7=8x-12
3x+3x-8=-12-7-7
-2x=-2
x=-2/(-2)
x=1
