( A u B) would be the combination of both sets.

Since both sets have all distinct numbers, just add the 2 sets together.

4 + 7 = 11

The purple pathers helipad is 1/3 of a mile from the control center we'll drop the food when it's 1/4 of the way there how many

AlexFokin [52]

Answer:

1/12 of a mile.

Step-by-step explanation:

1. Find a common denominator. In this instance, we can use the denominator of 12 because both 3 and 4 are multiples of 12.

2. Multiply each fraction (numerator and denominator) to convert them.

1/3(4/4) = 4/12

1/4(3/3) = 3/12

3. Subtract.

4/12－3/12 = 1/12

4. Determine all unknown sides and angles to 1 decimal place.

Ksju [112]

Answer:

The unknown sides are 60.81cm and 51.57cm while the unknown angle is 58degrees

Step-by-step explanation:

4a) Given the following

Opposite side = 38cm (side facing the given angle)

Required

Adjacent and hypotenuse side

According to SOH CAH TOA

$tan \theta = \frac{opp}{hyp}\\tan 32=\frac{38}{hyp}\\hyp=\frac{38}{tan 32}\\hyp=\frac{38}{0.6249}\\hyp= 60.81cm$

Next is to get the adjacent

$Cos 32=\frac{adj}{60.81}\\adj=60.81cos32\\adj=60.81(0.8480)\\adj= 51.57cm$

Next is to get the missing

Since sum of angle in the triangle is 180degrees

32 + 90 + x = 180

122 + x = 180

x = 180 - 122

x = 58degrees
