2-(-4)
--------= 6
-1-7 ---= 3/4

y=3/4x
-4=3/4 (7)+b
-4=21/4+b
-4-21/4= -37/4
21/4-21/4=0
y=3/4x-37/4
Which ever expression is 3x + 21 + 10 ..... 21 + 10 = 31 .... So it'll be 3x + 31 .
Answer:
First angle is 45 and the second angle is 60
Step-by-step explanation:
150 + 105 = 255
360 - 255 = 105
the ratio is 3:4 I add the ratio so 7
105 / 7 = 15
The first angle with the ratio of 3 is 15 x 3 = 45
The second angle with the ratio of 4 is 4 x 15 = 60
