Answer:
SSS
Step-by-step explanation:
The sides of the smaller triangle equal the sides of the larger triangle when you multiply them by six, so they are parallel.
Cos30 = sin(90 - 60) = √3/2, because cos and sin are complements
cos120 = cos(180 - 60) = -cos60 = -1/2
Answer:
and 
Step-by-step explanation:
Given:
.......................... equation i
........................ equation ii
since y is equals to the two functions , we can equate the two values of y . That is , equate equation i and ii , we have
Add 
to both sides , we have
subtract 3 from both sides , we have
divide both sides by 4 , then
substitute into equation i to get the value of y , that is
Therefore :
and
Answer for 1 is 22 degrees
Answer:
y=5x-12
Step-by-step explanation:
y=5x+3, and just replace the x and y to get the b. The slope is the same.
1) 3=5(3)+b
2)3=15+b
3)-12=b
4) y=5x-12
