Using the definition of angles on a straight line, the measure of angle BEC is: 62°.
<h3>What are Angles on a Straight Line?</h3>
Angles that lie on a straight line add up to 180 degrees.
Thus, given that EB bisects ∠AEC, therefore:
m∠BEC = 1/2(180 - m∠CED)
Plug in the values
m∠BEC = 1/2(180 - 56)
m∠BEC = 1/2(124)
m∠BEC = 62°
Thus, using the definition of angles on a straight line, the measure of angle BEC is: 62°.

Answer:
A triangular scarf is an isosceles right triangle.
Step-by-step explanation:
Given: A scarf is a triangle with two perpendicular sides that are the same length.
We have to name which two terms describe a triangular scarf.
Isosceles triangle is a triangle with length of two of its sides equal.
Right angled triangle is a triangle in which one angle is a right angle.
Given :
The two sides of scarf are perpendicular to each other.
Thus, the angle formed between them is 90°. Hence, right angled triangle.
Also, length of two sides are same, Hence isosceles triangle.
Thus,a triangular scarf is an isosceles right triangle.

Answer:
x= 11
Step-by-step explanation:
4x+5/7 =2x-1/3
multiply both of the equation by 7 first
4x+5/7 times 7 = 2x-1/3 times 7
4x+5= (2x-1)7/3
now multiply 3 to both sides
3(4x+5)= (2x-1)7/3 times 3
3(4x+5)= (2x-1)7
now you should distribute on both sides
(4x times 3)+(5 times 3)= (2x times 7)-( 1 times 7)
12x+15= 14x-7
subtract 12x from both sides
12x-12x+15= 14x-12x-7
15= 2x-7
add 7 to both sides
15+7= 2x-7+7
22= 2x
divided both sides by 2
22/2 = 2x/2
11=x
