Alternate interior angles theorem.
<u>Step-by-step explanation:</u>
By using the definition of Alternate Interior Angles theorem, we can say that If a transversal cuts any two parallel lines, then those pairs of alternate interior angles are seems to be congruent.
So in the given triangle,
∠4 ≅ ∠2
∠5 ≅ ∠3
Sum of all the angles in a triangle = 180°
∠1 + ∠2 + ∠3 = 180°
Since from the above congruence, we can write that
∠1 + ∠4 + ∠5 = 180°
Hence proved.
Answer:
375 seats
Step-by-step explanation:
500/4=125
125 times 3= 375
Answer:
Angle B is 44 degrees.
This is a right triangle.
Steps:
The sum of interior angles in a triangle equals 180 degrees. The given triangle is a right triangle.
So A + B + C = 180
We are given A and C.
46 + B + 90 = 180
B + 136 = 180
180 - 136 = 44
1. D linear
2. A quadratic
3. B exponential
4. C rational
