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:
217°
Step-by-step explanation:
the tangent ratio is positive in the first and third quadrants.
37° is the angle in the first quadrant
then the angle in the third quadrant is
180° + 37° = 217°
Answer:
The answer is (D) ⇒ the time at which the egg reaches the ground
Step-by-step explanation:
∵ h(x) = -16x² + 35 ⇒ x is the time in seconds
∵ The zeroes of the expression means the value of x when h(x) = 0
and h is the height of the egg form the ground
∴ -16x² + 35 = 0
∴ 16x² = 35
∴ x² = 35/16 = 2.1875
∴ x = √2.1875 = 1.479
∴ The egg reaches the ground after 1.479 sec.
∴ The zeroes of the expression means the time at which the
egg reaches the ground
