Answer:
85°
Step-by-step explanation:
- Angles in a triangle add up to 180°.
- 40° + 55° = 95° - This means that there is already 95° in the triangle
- To find the missing angle (angle 1) we need to do 180 - 95 which is 85°.
Hope this helps!
What do you mean? You just need to prove there are two angles and the side between these two angles are the same in each triangle. One of the possible <span>combinations could be </span>∠BAC=∠FDE, ∠ABC= ∠DEF, and AB=DE.
Answer:
x = 11
Step-by-step explanation:
69° + (2x - 1)° = 90° (complementary angles)
69 + 2x + 1 = 90
Add like terms
69 - 1 + 2x = 90
68 + 2x = 90
Subtract 68 from each side
68 + 2x - 68 = 90 - 68
2x = 22
Divide both sides by 2
2x/2 = 22/2
x = 11
