Question 7

<h3>Answer: A) 15</h3>

---------------------

Work Shown:

angle B = angle D = 56

angle C = angle F = 64

The missing angle A adds with B and C to get 180

A+B+C = 180

A = 180-B-C

A = 180-56-64

A = 60

Since angles B and D are congruent, and C and F are congruent, this must mean angle A = angle E. I'm using the angle angle (AA) similarity rule.

angle E = angle A

3x+15 = 60

3x = 60-15

3x = 45

x = 45/3

x = 15

Side note: I'm not sure why your teacher marked angle E as the same as angles C and F.  They should have used another angle marker to indicate that angles A and E are the same.

================================================

Question 8

<h3>Answer: B) 17</h3>

------------------------------

Work Shown:

Triangle ABC is congruent to triangle EDF. The order is important. We have A first, then B, then C for ABC. Also, we have E first, then D, then F for EDF.

Therefore, we have these three pairings

  • angle A = angle E
  • angle B = angle D
  • angle C = angle F

We'll first need angle C

A+B+C = 180

C = 180-A-B

C = 180-42-108

C = 30

which we'll then solve for x

angle F = angle C

4x-4 = 30

4x = 30+4

4x = 34

x = 34/4

x = 8.5

which doubles to

2x = 2*8.5

2x = 17

Solve the system using elimination.<br> 2x + 3y = -2<br> 3х – 6у = 18
Mashutka [201]

Answer:

x = 2 and y = -2

Step-by-step explanation:

We must first eliminate the y-variable:

2x + 3y = -2

3x - 6y = 18

4x + 6y = -4

3x - 6y = 18

_________

7x = 14

x = 2

Since we know x=2, we plug that back into one of the original equations to find y:

2x + 3y = -2

2(2) + 3y = -2

4 + 3y = -2

3y = -6

y = -2

Therefore, x = 2 and y = -2

16=-2p-18 what does p =​
rodikova [14]
Add 18 to both sides

16+18=2p

Simplify 16+18 to 34
34=2p

Divide both sides by 2
34/2=P

Simplify 34/2 to 17

17=P


Therefore your answer is
P=17

Deffense [45]

Answer:

  b. 30°

Step-by-step explanation:

In quadrilateral OTPR, angles O and P are supplementary.

  angle P = 180° -angle O = 180° -150°

  angle P = 30° . . . . matches choice B
