Answer:
x = y = 4
Step-by-step explanation:
Using the cosine ratio in the right triangle and the exact value
cos45° = , then
cos45° = = ( multiply both sides by 8 )
8 × cos45° = x , then
x = 8 × = 4
The third angle in the triangle = 45° ( sum of angles in triangle )
Then the triangle is isosceles with congruent legs, thus
x = y = 4
Answer:
4
Step-by-step explanation:
3(a+2) = 26-2a
3a+6=26-2a
3a+2a=26-6
5a=20
a=20/5
a=4
C. there is neither a correlation nor causation between two variables
