Answer:
-3.5
Step-by-step explanation:
2x+21/2=x+7
2x + 10.5 = x + 7
-x -x
x + 10.5 = 7
-10.5 -10.5
x = -3.5
Step-by-step explanation:
<YOZ = 60°
When two lines intersect each other, then four angles are formed. The angles that are opposite to each other at the intersection point are known as <em>vertically</em><em> </em><em>opposite</em><em> </em><em>angles</em><em>.</em><em> </em>VERTICALLY OPPOSITE ANGLES ARE ALWAYS EQUAL.
If < VOX = 90⁰, then <VOW = 60⁰.
<VOW and <YOZ are vertically opposite angles.
<h2>
It takes 3.31 minutes the airplane to climb to a height of 14,000 feet</h2>
Step-by-step explanation:
Angle with horizontal = 15°
Velocity of plane = 272 feet per second angle of ascent is 15 degrees
Velocity of plane = 272 cos 15 i + 272 sin 15 j = 262.73 i + 70.40 j ft/s
Vertical velocity = 70.40 ft/s
Vertical displacement = 14000 ft
We have
Vertical displacement = Vertical velocity x Time
14000 = 70.40 x Time
Time = 198.87 seconds = 3.31 minutes
It takes 3.31 minutes the airplane to climb to a height of 14,000 feet
A^2=c^2 - b^2
a^2=169-144
a=root 25
a=5
The answer will be 5
