Wendy goes to the gym every 4 days and swims every 6 days. If she went to the gym and swam today, in how many days will she do b
Mice21 [21]

In 12 days, Wendy will do the both again.

Step-by-step explanation:

Given,

Wendy goes to gym every 4 days

Wendy swims every 6 days

We will find the least common multiple of both the numbers in order to determine the number of days in which she will do both.

4 = 4,8,12,16,20,....

6 = 6,12,18,24,.....

Therefore;

The least common multiple of 4 and 6 is 12.

Thus,

In 12 days, Wendy will do the both again.

Find each measure.<br> m1, m2, m3
lyudmila [28]

Answer:

second option

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

∠ 1 and 33° form a straight angle and are supplementary, thus

∠ 1 = 180° - 33° = 147°

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

The third angle in the triangle on the left is

180° - (33 + 47)° = 180° - 80° = 100°, thus

∠ 2 = 180° - 100° = 80°

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

∠ 2 and the angle in the triangle form a straight angle and are supplementary,

angle = 180° - 80° = 100°

The third angle in the triangle on the right is

180° - (100 + 48)° = 180° - 148° = 32°, thus

∠ 3 = 180° - 32° = 148° ( straight angle )

Thus

∠ 1 = 147°, ∠ 2 = 80°, ∠ 3 = 148°
