Which set of three angles could represent the interior angles of a triangle?
2 answers:
Answer:
49°, 59°, 72°
Step-by-step explanation:
Angles of a triangle must add up to 180°.
49° + 59° + 72° = 180°
28° + 58° + 62° = 148°
39° + 89° + 108° = 236°
45° + 70° + 85° = 200°
Only the first set could represent the interior angles of a triangle.
Answer:
The first choice.
Step-by-step explanation:
The 3 angles must add up to 180 degrees.
49 + 59 + 72 = 108 + 72 = 180.
So it is the first choice.

Answer:
m=10
w=15
Step-by-step explanation:
m + w = 25
3m + 4w = 90
Let's do substitution, first by solving the first equation for m.
m = 25 - w
Substitute!
3(25 - w) + 4w = 90
75 - 3w + 4w = 90
w = 15
m = 25 - 15 = 10
That's all you need to do
