Answer:
12+2√6+2√10
Step-by-step explanation:
(√2+√3)² + (√5+√2)²=2+3+2√6+5+2+2√10=12+2√6+2√10
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°
Answer:
39 2/3
Step-by-step explanation:
9x-4=5x-6
+4 +4
9x=5x-2
-5x-5x
4x=-2
divide by 2 on both sides
x=-2 or
x= 4/9
