Answer:

34. A negative number multiplied by a positive number will always have a negative product. The right answer should be -8.14.

35. When dividing fractions, you have to use the same-change-flip rule. The work should be like this: -1/4 x 2/3 = -2/12 = -1/6. The correct answer is -1/6.

36. In this problem, you need to convert 2 1/5 into a decimal, then multiply by -30. (2.2 x -30) The answer is -66 degrees.

Answer:

Part a) <1=72°

Part b) <2=108°

Part c) <3=72°

Part d) <4=108°

Step-by-step explanation:

<1+108°=180° -----> by supplementary angles

<1=180°-108°=72°

step 2

Find the measure angle 2

we know that

<2=108° -----> by corresponding angles

step 3

Find the measure angle 3

we know that

<3=<1-----> by corresponding angles

<3=72°

step 4

Find the measure angle 4

we know that

<4=108° -----> by alternate exterior angles

Answer:

5 is congruent, 6 is not congruent

Step-by-step explanation:

In 5, both shapes have the same side lengths. This means their areas are the same, making them congruent.

In 6, the shapes do not have the same side lengths. This means their areas are not the same, making them not congruent.
