Mark the statements that are true. a. an angle that measures is a reflex angle. b. an angle that measures 65 is an acute angle. c. an acute angle measures less than . d. an angle that measures 300 is an obtuse angle.

B and D

Step-by-step explanation:

We are given four statements

Starting with correct options :

B is correct statement because of the definition of Acute Angle  .

Definition of Acute Angle : An angle that measures less than 90°  is known as acute angle.

Since 65°∠90°

So, B is the correct statement  .

D is correct statement because of the definition of Obtuse Angle.    

Definition of Obtuse Angle : An angle that measures more than 90°  is known as Obtuse Angle.

Since  90°∠300°

So, D is the correct statement  .

Option C is incorrect because it is incomplete .

Option A is incorrect because it is incomplete .

0 is its x and y coordinate

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
