Answer:
? = 110
Step-by-step explanation:
We know the one angle is 25 and the other is 45 because the 90 degree angle that is cut off perfectly in the middle.
All angles of a triangle always adds up to 180
Add all the known angles 25 + 45 = 70
Than subtract 180 - 70 = 110
Answer:
∠ 4 = 140°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ 4 is an exterior angle of the triangle, then
∠ 4 = ∠ 1 + ∠ 2 ( substitute values )
11x + 8 = 6x + 7 + 4x + 13
11x + 8 = 10x + 20 ( subtract 10x from both sides )
x + 8 = 20 ( subtract 8 from both sides )
x = 12
Then
∠ 4 = 11x + 8 = 11(12) + 8 = 132 + 8 = 140°
The answer is easy it is x=5
Answer: 3x + (-4) = x + 2
