First find angle EBC.
The are for a triangle is 180 degrees.
It is a right triangle and has a right angle.
180 - (90 + 50)
180 - 140
angle EBC IS 40
NOW FIND X
The line is 180 degrees.
180 -40 = 140
X = 140 DEGREES

<h3>What is the Area of a Polygon?</h3>
The area of a polygon is one that is defined as the measurement of the given area that is known to be covered by it.
Note that to calculate the area, it will be
Area = 1/2 (5 + 1) x 3 = 9 units²
Thus the answer of 9 units is correct.

Answer:
x=57
Step-by-step explanation:
63+60= 123
A triangle is 180 degrees
180-123= 57
x=57
(1/5) / 4.5 = 2 / m....1/5 mile to 4.5 minutes = 2 miles to m minutes
cross multiply
(1/5)(m) = (2)(4.5)
1/5m = 9
m = 9 * 5/1
m = 45 minutes <===
