Answer:
- Angle 1 = 139°
- Angle 2 = 41°
- x = 29; exterior angle = 131°
Step-by-step explanation:
These problems let you make use of the fact that the sum of the remote interior angles is equal to the exterior angle.
__
1. 53° +86° = ∠1
139° = ∠1
__
2. ∠2 +92° = 133°
∠2 = 133° -92°
∠2 = 41°
__
3. (x +9)° +93° = (4x+15)°
87 = 3x . . . . . . . . . . . . . . . . subtract x+15°
29 = x . . . . . . . divide by 3
The exterior angle is ...
(4x +15)° = (4·29 +15)° = 131° . . . exterior angle
Answer:
C. 61
Step-by-step explanation:
Two sides are equal, so the triangle is an isosceles triangle.
Both base angles are equal.
Angles in a triangle add up to 180 degrees.
58 + x + x = 180
58 + 2x = 180
2x = 122
x = 61
97+x=27+64
x=27+64-97
x=-6
(Hopefully this is correct)
Answer:
11 inches
Step-by-step explanation:
Let the level of ground level be g
On first day, amount of snow melted by 3 inches
So, level of ground melted= (g- 3) inches
Next day, amount of snow melted by 8 inches
So, level of ground level melted = (g- 3-8 )inches
Hence, total change in the ground level = ( g- 11) inches
Hence, amount of snow on ground level melted by 11 inches
Hence, the correct answer is 11 inches
