Answer:
50°
Step-by-step explanation:
I am assuming that the shape is a right triangle.
All interior angles of a triangle add up to 180°.
[tex]x + 40 + 90 = 180\\\rule{150}{0.5}\\x + 130 = 180\\\\x + 130 - 130 = 180 - 130\\\\\boxed{x = 50}[/tex]
The missing angle should be 50°.
Hope this helps.
Answer:
[tex]\boxed{50 }[/tex]
Step-by-step explanation:
A triangle is the simplest polygon. It is a two-dimensional shape with three straight sides forming an interior, closed space. It has three interior angles.
1. Subtract the two known angles from 180°
2. Plug the two angles into the formula and use algebra:
[tex]\boxed{a+b+c=180}[/tex]
3. Subtract
[tex]\boxed{180-40 =140}[/tex]
[tex]\boxed{140-90=50}[/tex]
[tex]c=50[/tex]
Therefore, The Answer is 50
