Answer:
1. (5x - 2) + (2x - 2) + x =
2. m<J =
3. m<K =
4. m<L =
Step-by-step explanation:
Generally, the sum of angles in a triangle = .
So that;
m<J + m<K + m<L =
(5x - 2) + (2x - 2) + x =
5x + 2x + x -2 -2 =
8x - 4 =
8x = + 4
8x = 184
x =
x =
Thus,
m<J = (5x - 2)
= 5(23) - 2
=
m<K = (2x -2)
= 2(23) - 2
=
m<L = x
=
Answer:
Step-by-step explanation:
For plane A,
Equation that represents the relationship between time 'x' and distance 'y' is,
y = 470x
By comparing this equation with the slope-intercept form of the equation,
y = mx + b
m = slope = 470
b = 0
Here, slope represents the speed of plane A.
Therefore, speed of plane A = 470 mi per hour
For plane B,
From the given table,
Slope of the graph =
=
= 480
Speed of plane B = 480 miles per hour
Since, speed of plane B is more than plane A,
Plane B is flying faster.
