Answer:
135°
Step-by-step explanation:
Lines L and M are not shown as parallel, but we have to assume they are if we're to answer this question. That makes angle 2 and the one marked 135° alternate interior angles, hence congruent.
∠2 = 135°
_____
<em>Additional comment</em>
Angle 1 = 45° and x = 20.
Y= 25/4 or if you want it in decimal form it’s 6.25
As x approaches either positive or negative infinity, y will approach positive infinity.
This is because x^2 will grow large much quicker than b*x, so it has more importance. So when considering the limit, we can imagine that the equation looks like this:
y = x^2
This equation will go to infinity for x approaching both negative and positive infinity.
Answer: 
Step-by-step explanation:
Given: The anchor for the wire is 93 m away from the base of the turbine.
It connects to the turbine 236 m above the ground.
Let x be the angle of elevation for the guy wire
By trigonometry,
Nora's speed (5*8)m²/2h= 20 m²/h.
Zack's speed (4*9)m²/3h= 12 m²/h
Together for 1 h they paint (20+12) m²/h=32m²/h
Given area (10*12)m²=120 m²
120m² *1h/32m² = 3.75 h (3h 45 min) to paint 10m*12m together.
