It'd be AEC, the vertex are just the lines that create the point E
Answer:
The triangles are similar by AAA
Step-by-step explanation:
Here, we want to show that the two triangles are equal
for each of the two, we can see that we have two angles
mathematically, the sum of the angles in a triangle is 180
For the bigger one,
The last angle will be;
180-85 -50 = 45
For the smaller one;
the last angle will be;
180 - 85 - 45 = 50
The angles in the bigger are 45,50 and 85
The angles in the smaller are 45,50 and 85
This shows that both triangles are completely congruent by AAA (angle-angle-angle)
Answer:
x = 0°
Step-by-step explanation:
Given
- 2 + 6cosx = 8 - 4cosx ( add 4cosx to both sides )
- 2 + 10cosx = 8 ( add 2 to both sides )
10cosx = 10 ( divide both sides by 10 )
cosx = 1 , thus
x =
(1) = 0° for 0° ≤ x ≤ 180°
Draw a graph with integer lines going vertical and horizontal. Make sure the integer lines have all the numbers in the coordinates. Find where the numbers line up on the graph.
