In picture 1 we got a right triangle on the left. Two given angles are the 90° and a 30°. When we calculate the remaining angle we get:
30 + 90 + x = 180
120 + x = 180
x = 60

The bottom right angle of the right triangle is 60°.

At the bottom, we see a straight line with 3 angles on it. Because that angles made up a straight line, we know their sum is equal to 180°. When we convert that into an equation: 60 + 70 + y = 180

Simplify:
130 + y = 180
y = 50

We learned that the left bottom angle of the triangle on the right equals 50°.

At the triangle on the right we have two angles known: 50°, and 85°. We can find the third angle by setting their sum equal to 180: 50 + 85 + ? = 180

Simplify:
135 + ? = 180
? = 45


For picture 2, we know that those two triangles have congruent angles in the middle. The two angles in the middle are what we call 'vertical' angles.

Because their one angle is equal, their remaining two angles' sum needs to be equal to each other. So 24 + ? = 27 + 26

When we simplify this:
? = 53 - 24
? = 29

So, the ? is 29.

(I used x and y but I made them up)

Distance between 2 airports 1,505 miles. Average speed of airplane 420 mph. Flight time hours
-BARSIC- [3]
For this case we have the following definition:
 d = v * t
 Where,
 d: distance
 v: speed
 t: time
 Clearing the time we have:
 t = d / v
 Substituting values:
 t = 1505/420
 t = 3,583 hours
 Answer:
 
Flight time hours:
 
t = 3,583 hours
