Answer & Step-by-step explanation:
We are given that m∠1 = m∠2. We are to prove that line l is parallel to line m. So, let's make a proof. Your first statement should always be the given statement. You are given the statements. All we have to do is find the reasons for those statements.
- m∠1 = m∠2 → Given
- m∠1 = m∠3 → Vertical angles are equal
- m∠2 = m∠3 → Substitution
- l ║m → If corresponding angles are equal, then lines are parallel
Answer:
Quadratic equations have the form:
ax^2 + bx + c = 0
So, a = 1 b = -3 and c = -2
None of the 4 choices have "a" equal to one.

Answer:
b
Step-by-step explanation:
Would it be two equilateral triangles?
I'm sorry if this doesn't help I don't really know what type of triangle that is.
Surface area is the sum of area of all surfaces.
In the given diagram , we have two identical triangles , with height = 20 cm and base = 25 cm. Area of triangle = (1/2)*base * height.
So for the given triangle , area = 2*(1/2)*20*25 = 500 cm square .
We have a bottom rectangle whose area is 25*40 = 1000 cm square. A sideby rectangle, whose area is 35*40= 1400 cm square and a backwards rectangle, whose area is 20*40 = 800 cm square.
So the surface area = 500+1000+1400+800 =3700 cm square.
