What is m∠a ? enter your answer in the box. ° 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.

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.

25 questions , because they start with 100.  

350-100=250 .  

. 250/10=25

step-by-step explanation:

first take off 100, then what x 10 = 250? that is your answer. (25)

so, converting firstly the mixed fractions to improper fractions and then "adding".
