It is 19 degrees (19 times 2 equals 38. 38+10=48
Answer:
Step-by-step explanation:
There are 3 possible triangles to find there within what appears to be one triangle. And since they are all part of the same largest triangle, they are also all similar. Just because 2 shapes may be triangles, so NOT mean they are automatically similar. Remember that!
The largest triangle is ΔABC
The triangle on the "left" is ΔADB, and
The triangle on the "right" is ΔCDB
The answer is
The answer is <span>b. x=-2 </span>
The area (A) of a parallelogram with height h and base b is:
A = b*h
We have:
b = 5
h = x + 6
A = 20
A = b * h
5 * (x + 6) = 20
x + 6 = 20 / 5
x + 6 = 4
x = 4 - 6
x = -2
