Answer:
d
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the 2 given angles from 180 for ∠ A, that is
∠ A = 180° - (38 + 18)° = 180° - 56° = 124° → d
its c
just add 38 plus 18
Answer:Top right
Because they are all the same V shape, we look to the slope for the answer.
Because the Y-intercept in this equation is 0.5, we look for the graph in which it is centered and at 0.5
That would be the top right.
