Hi, pls help, i need to these questions answered for my math hw, it'll count as a test. tysm in advance. 1. Find all angles, 0≤θ<360, that satisfy the equation below, to the nearest 10th of a degree.
2cos^2θ−cosθ=0
2. Find all angles, 0≤θ<360, that satisfy the equation below, to the nearest 10th of a degree.
8sinxcosx=−5cosx
3. Assume that θ is a positive acute angle.
Given: cosθ= 12/37
Find: cos2θ
4. For positive acute angles A and B, it is known that tanA= 15/8 and cosB= 12/13. Find the value of cos(A+B) in simplest form.
5. If cos B= 1/2, then what is the positive value of sin1/2B, in simplest radical form with a rational denominator?
6. Two forces of 630 newtons and 170 newtons act simultaneously on an object. The resultant forms an angle of 59 with the 170-newton force. Find the angle formed between the two original forces, to the nearest degree.

two data sets with the same median will not have the same varaibility

step-by-step explanation:

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.

39mph

step-by-step explanation:

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
