Answer:
Y = 40
Step-by-step explanation:
First find the measure of V
The sum of the angles of a triangle equal 180
U+V+W =180
70+Y+70 =180
140+U =180
U = 180-140
U = 40
Since the triangles are similar
V = Y
40 = Y
Answer:
Step-by-step explanation:
b//c; a is transversal
5x + 5 + 115 = 180 { 5x+5 and 115 are supplementary angles}
5x + 120 = 180
5x = 180 -120
5x = 60
x = 60/5
x =12
Answer:
Yes
Step-by-step explanation:
To form a triangle : The sum of any two side lengths must be bigger than then the third side length and their difference smaller than the third side length.
19.6 + 1.6 > 18.7
19.6 - 1.6 < 18.7 and so on.
Associative an example of this property is 3x4x6=4x3x6
