Answer:False, true, true, false
Step-by-step explanation:
The first one is false because 2 & 5 equal 180 together. B is true because they equal the same thing. C is true because they equal 180 together. And D is false because those don’t equal 180.
SINCE THATS AN ISOSCELES TRIANGLE:
AB=BC
SO 3x-4=5x-10
But we have to find x
3x-4=5x-10
Minus 3x on both sides
-4=2x-10
Add 10 on both sides
6=2x
Divide 2 on both sides
3=x
So x is 3
Now since we are looking for side AB which is 3x-4
Substitute in 3 as x
3(3)-4
9-4=5
So 5 is the answer.
Brainlist would be much appreciated!
The constant is -1 because a constant is a fixed number. You do -7+6=-1 to get the constant
Answer:
39
Step-by-step explanation:
Let assumed that the smaller number is x.
Since it says that the greater number is 4 times the smaller number,
the greater number is 4x.
Given that the difference is 117.
4x - x = 117
3x = 117
x = 39
