Answer:

ok so u know that all triangles in the inside are equal to 180

Step-by-step explanation:

1. 180-162= 18 angle a is 18, now to solve for b 180-122-18=40, angle b is 40

2.180-171=9 angle a is 9, now to solve for b 180-128-9=43, angle b is 43

3.180-35-22=132 angle c is 132, now to solve for angle d 180-22=158, angle d is 158

4. 180-20-29=131 angle c is 131, now to solve for angle d 180-20=160, angle d is 160

The exact value of cos 13pi/8 is
Naily [24]

Answer:

answer is : Cos(13pi/8) = 0.3826  

Step-by-step explanation:

We have, Cos (13pi/8)

Since 13pi/8 can be shown as 3pi/2 < 13pi/8 < 2pi

Hence 13pi/8 lies on fourth quadrant.

In fourth quadrant cosine will be positive.

Cos (13pi/8) = cos(3pi/2 + pi/8)

applying formula cos(A+B) = cos A cosB - sinAsinB

i.e Cos(3pi/2 + pi/8) = cos(3pi/2)cos(pi/8) - sin(3pi/2)sin(pi/8)

∵ Remember cos(3pi/2) =0 , sin(3pi/2) = -1

     Cos(3pi/2 + pi/8) = 0 cos(pi/8) - (-1)sin(pi/8)

     Cos(3pi/2 + pi/8) = 0  + 0.3826

      Cos(3pi/2 + pi/8) = 0.3826

Hence we got Cos(13pi/8) = 0.3826

Sara can type 90 words in 4 minutes.About how many words would you expect her to type in 10 minutes?
Alexus [3.1K]
90 words in 4 minutes is the same as 45 words in 2 minutes because you divide both sides by 2.  2 goes into 10, 5 times, so 45x5=225.
You can expect her to type 225 words in 10 minutes.
