Answer:
The largest angle is 90 degrees
Step-by-step explanation:
The three angles of a triangle add to 180
The ratio is 10 : 3: 7
Multiply each by x
10x, 3x 7x
Add them together and set equal to 180
10x+3x+7x = 180
Combine like terms
20x = 180
Divide by 20
20x/20x =180/20
x = 9
The largest angle is 10x
10*9 = 90
The largest angle is 90 degrees
probability (brown or green card) = total number of cards of brown and green / total number of cards of all color
so
total number of brown and green card = 12 +3 = 15
total numbers of card = 12+5+3=20
probability (brown or green) = 15/ 20 = 3/4 = 0.75
Answer:
Not isosceles
Step-by-step explanation:
45 - (17 + 19) = 9
9 is the side length which is not equal to either of the other sides so the triangle is scalene.
The scale factor would be 1.25 because each segment is the same in this triangle
