Find the angle between the given vectors to the nearest degree.
konstantin123 [22]

Answer:

c. 108.4

Step-by-step explanation:

cos theta = (u dot v)/ (||u||  ||v||)

where dot stands for dot product and || || is the magnitude

u = (1,5)   v= (7,-4)

u dot v = (1*7 + 5*-4)  = 7-20 = -13

||u|| = sqrt( 1^2 +5^2) = sqrt(1+25) = sqrt(26)

||v|| = sqrt(7^2 + (-4)^2) = sqrt(49+16) = sqrt(65)


cos theta = -13/ sqrt(26) sqrt(65)

cos theta = -13 /sqrt(1690)

theta = arccos (-13/sqrt(1690))

theta = 108.43

Combining like terms with rational coefficients <br> 7/8m+9/10-2m-3/5
nikklg [1K]

Answer:

Ah yes, one of my favorite topics.

Step 1: Which ever fraction comes first, you will solve it first. For this question, focus on doing \frac{7}{8}m-2m first. Afterwards, do \frac{9}{10}-\frac{3}{5}

Step 2: First one equals to 1.125. Next, find the LCD (lowest common dominator, which is 10). \frac{9}{10} -\frac{6}{10}=\frac{3}{10}

Step 3: 1.125+3/10

Find the value of x.
kirza4 [7]
Hey there :)

Here we need to use Trigonometry!

The given angle is 61°
The opposite to the angle is 22 
So x is the adjacent

The trigonometric ratio that uses opposite and adjacent is tan
( I have uploaded a picture to help you )


tan α = \frac{opposite}{adjacent}
tan 61 = \frac{22}{adj}
adj = \frac{22}{tan(61)}
adj ≈ 12.19 ≈ 12

x = 12
