Answer:
The vertex angle is 94 degrees
Step-by-step explanation:
Let the vertex angle be x
Mathematically, the base angles of an isosceles triangle are the same
So if one of the base angles is 43 degrees, then the other base angle would be 43 degrees too
Mathematically, the sum of angles in a triangle is 180 degrees
Thus;
43 + 43 + x = 180
x = 180-86
x = 94 degrees
Answer:
9.6
Step-by-step explanation:
ratio means you divide one by the other
240/25
9.6
Answer:
its the second expression
Step-by-step explanation:
Lets say you have a question such as 7x+1=15.
First you have to start with the addition or subtraction because of PEMDAS. In order to get rid of the +1, you have to subtract 1 from it and do the same thing to the number on the other side of the equal sign.
7x+1-1=15-1
Which leaves you with
7x=14
What you want to do is get the variable by itself so, since the variable is basically multiplying itself by the coefficient, you want to divide the 7x by 7 to get rid of the coefficient. Make sure to do the same for both sides of the equation!
7x/7=14/7
x=2
Thats the answer.
Hopefully you can figure this out on your own problem.
