If the area of one is 20, that the area of 30 is 20*30=600 square inches.
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
The answer to your question would be D.
there is no way to tell if any of the other options are true or not so the only possible choice would be D.
Hope this helps! :)
