Answer:
A
Step-by-step explanation:
-22x=-4x+28
-18x=28
x=-28/18=-14/9
Answer:
, which simplifies into 
Step-by-step explanation:
You divide both sides by 35 and get
Step-by-step explanation:
the distance of a vertex on the 2 outgoing sides to the touching points with the inscribed circle is the same for both sides.
and that applies to all 3 vertexes.
so, we know for the top left vertex the distance to both touching points is 4.
that means the distance to the touching points from the bottom left vertex is 7-4 = 3.
and that means that the distance to the touching points from the bottom right vertex is 16-3 = 13.
so, x = 13
it is the distance to one of the touching points for the bottom right vertex.
and the perimeter of the triangle is therefore
7 + 16 + (13 + 4) = 40
Answer:
x=50
Step-by-step explanation:
Because these angles are vertical, they are equal. Let’s find x.
So, x=50.
A) to find the difference you have to subtract one from the other (53-(-41)=91)
b) 15
