36°, 72°, 72°
let x be the third angle then each of the other 2 angles is 2x
the sum of the angles in a triangle = 180° thus
x + 2x + 2x = 180
5x = 180 ( divide both sides by 5 )
x =
= 36
the angles are 36°, 72° and 72°
Answer:5.1
Step-by-step explanation:
6x + y = -2
y = -3x + 1
Substitute the value of y in first equation,
6x -3x + 1 = -2
3x = -2-1
x = -3/3
x = -1
Now, Substitute it in 2nd equation,
y = -3(-1) + 1
y = 3+ 1 = 4
Coordinates would be: (-1,4) Mark that point and join with origin.
Hope this helps!
Answer:
1,542,682 cm^3.
Step-by-step explanation:
The scale factor = √169:√289
= 13:17
So the Volume ratio is 13^3:17^3
So the volume of the larger solid is 689,858 * (17^3/13^3)
= 1,542,682 cm^3.
