Look at the following bellow. Which of the following statements could be stepped in prove that vertical angles are congruent

1. <APC ~ <DPB because angles complementary to the same angle are congruent to each other.

2. <APC ~ <DPB because angles supplementary to the same angle are congruent to each other.

3.<APC ~ <DPB because angles adjacent sent to the same angle are congruent to each other.

4. <APC ~ <DPB because the angles formed by the same pair of intersecting lines are congruent to each other.

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

2,160 π

step-by-step explanation:

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
