Answer:
x° =121°
Step-by-step explanation:
The inside angles of a triangle together must equal 180°. Therefore, 58° + 63° + n° = 180° if n equals the third angle inside the triangle. So,
180°-(58°+63°)=n°
180° - 121° = n°
59° = n°
Since the outside angle x and 59° must also equal 180°,
180° - 59° = x°
121° = x°
You can also find the exterior angle without finding the interior by adding the two other interior angles together.
58°+63°=x°
121°=x°
Convert "inches" to "feet" here. 30 in 1 ft 30
--------- = --------- = --------- ft
1 12 in 12
Now find the ratio of (30 ft / 12) to 9 ft:
30 ft
------
12 30
==== = ----------- Reduce this fraction; one way would be to
9 ft 12(9) write 30/9 as 10/3:
30 10
------- = ------------ = 5/18 (answer)
12(9) 12(3)
2(a^2+b^2).
A^2 but b^2 = c^2 (area of triangle)
A trapezoid is two triangles put together i just say multiply those together
