The size of the triangle is 55 degrees.
Answer:
x = 2√7
using Pythagoras theorem:
For the bottom part:
1. given
2. perpendicular lines makes a right angle
5. definition of complementary angles
sorry bout the others. idk how to word it so hopefully what I gave you helps
<u>Step-by-step explanation:</u>
The vertex form of an absolute value equation is: 
where
(h, k) is the vertex. In the given equation, 
, the h-value is 1/2 and the k-value is -2.
So, the vertex (h, k) = (1/2, -2)
the area of the triangle is 36
