Answer: The measure of angle A is 60 degree.
Explanation:
It is given that the Triangles A B E and D C E share vertex E. Angle B is 18 degrees. Angle C is 43 degrees. Angle D is 35 degrees.
According to angle sum property, the sum of angles of a triangle is always 180 degree.
In triangle CDE,





According to opposite vertical angle property.


Use angle sum property is triangle ABE.




Therefore, the measure of angle A is 60 degree.
Answer:

Step-by-step explanation:
Given

Consider the numerator:

Consider the denominator:

Hence, the fraction becomes

Consider the expression in brackets:

Divide:

Answer:
28 cm
Step-by-step explanation:
If the shape is a square, all the sides are equal. To find the area you multiply the length by the width. Since the area is 49 centimeters, find the square root of 49 to find the length of the length and the height of the square, which is 7. To find the perimeter, you add the lengths of all the sides of the square. 7+7+7+7=28.
