**Answer: three sets of value show 3 consecutive increases and they could be the intensities during fourth, fifth, and six visits:**

**66%, 69%, 72%; ****63%, 65%, 67%,** **and ****67%, 72%, 77%**

**Explanation: **

1) The program recommends a **constant intensity for 3 visits**, which is what the table shows:

Day Intensisty

1 63%

2 equal ⇒ 63%

3 equal ⇒ 63%

2) Hence, you have to determine the valid sets that meet the recommendation for the **fourth, fifth, and six visits**, which are the next three.

2) For the next three visits, the program recommensd **increasing intensities**.

There are three options that show 3 consecutive increases; they are:

**66%, 69%, 72%; ****63%, 65%, 67%,** **and ****67%, 72%, 77%**

Therefore, those are the choices that apply.

**Answer: 9 is A**

**Step-by-step explanation:**

area of triangle= 1/2 bh

1/2 of 8 is 4

4x10= 40

40x3= 120

1/2 of 8=4

4x6.9= 27.6

120+27.6=147.6 sq. m

**Answer:**

Two angles are called complementary when their measures add to 90 degrees. Two angles are called supplementary when their measures add up to 180 degrees.
