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.
4x+9=17
4x-9=-9
4x=8
4x/4=8/4
X=2
Distribute
72+-8p=192
Subtract 72 from each side
-8p=120
Divide each side by -8
And you get -15
Answer:
Answer: 98.12
Step-by-step explanation:
= 58.87 / 1 - 0.40
= 58.87 / 0.6
= 98.12
