I am assuming that you can only pick one answer per question.

Let's imagine there are two questions on the test. I would:

1) Consider the first question. How many possible ways could you answer it?

2) Consider the second question. How many ways can you answer that?

If you wrote out all the possibilities, how many combinations of answers would you get across the two questions?

Someone help me please! with questions 1-4 , geometry is not my strong suit
Mashutka [201]

Answer:

for the first 2 neither one is a polygon because a polygon has straight sides and is closed connections were the first shape has an open connection and the second shape has a curved line. for question i believe is 48 and question 4 is 145.

explanation.

for the last 2 problems their total equal 360 so you just add up all the side then subtract the number you got by 360 and that's your answer. ex.) 120 +130+ 62=312. 360-312=48

I need help i dont know what to do

Answer:

  ∠CAB = 28°

  ∠DAC = 64°

Step-by-step explanation:

What you do in each case is make use of the relationships you know about angles in a triangle and around parallel lines. You can also use the relationships you know about diagonals in a rectangle, and the triangles they create.

<u>Left</u>

Take advantage of the fact that ∆AEB is isosceles, so the angles at A and B in that triangle are the same. If we call that angle measure x, then we have the sum of angles in that triangle is ...

  x + x + ∠AEB = 180°

  2x = 180° -124° = 56°

  x = 28°

The measure of angle CAB is 28°.

__

<u>Right</u>

Sides AD and BC are parallel, so diagonal AC can be considered a transversal. The two angles we're concerned with are alternate interior angles, so are congruent.

  ∠BCA = ∠DAC = 64°

The measure of angle DAC is 64°.

(Another way to look at this is that triangles BCE and DAE are congruent isosceles triangles, so corresponding angles are congruent.)
