Answer:
a. 100 mph
b. 500 mph
Step-by-step explanation:
a.
Let the speed of Lindbergh's plane be x.
Today's planes are 5 times faster, so their speed is 5x.
Today's planes speed is 400 mph faster than Lindbergh's speed.
x + 400 = 5x
5x = x + 400
4x = 400
x = 100
Lindbergh's speed was 100 mph
b. 5x = 5 * 100 = 500
Today's planes fly at 500 mph
Answer:
A ) x < 48
B ) X less than or equal to 8
C ) 4/5

Answer:
It could be 14M.
Step-by-step explanation:
A to B is similar length, so that is why it could be 14M.
Option A:
m∠B = 28°
Solution:
Given ABC is a triangle on the circle.
m∠A = 62°
<em>The angle subtended by a diameter or a semicircle on any point of circle is 90°.</em>
AB is a diameter and C is the angle subtended on a diameter.
Therefore, m∠C = 90°.
Triangle sum property:
<em>Sum of the angles of the triangle = 180°</em>
m∠A + m∠B + m∠C = 180°
62° + m∠B + 90° = 180°
m∠B + 152° = 180°
m∠B = 180° – 152°
m∠B = 28°
The measure of angle B is 28°.
Hence Option A is the correct answer.
