Sin2alpha+cos2alpha-cos6alpha/sin4alpha+2sin²alpha-1<br><br> if alpha is -135°​
balandron [24]

Answer:

=  \frac{\sin(2 \alpha )  +  \cos(2 \alpha )  -  \cos(6 \alpha ) }{ \sin(4 \alpha )  + 2 { \sin }^{2}  \alpha  - 1}  \\  =  \frac{ \sin( - 270) +  \cos( - 270)  -  \cos( - 810)  }{ \sin( - 540)  + 2 { \sin }^{2}( - 135) - 1 }  \\  =  \frac{1}{ - 2}  \\  =  - 0.5

If cos Φ8/17 find the other five trigonometric ratios​
NeX [460]

Answer:

cos theta=8/17

8/17=A/H

finding O,

O ² + A² =H ²

(8)²+O²=(17)²

64+O²=289

O²=289-64

O²=225

O=√225

O=15

we know that H=17, A=8, O=15

therefore, the other trigonometric ratios are

sinФ=O/H=15/17

tanФ=O/A=15/8

cosecФ=H/O=17/15

secФ=H/A=17/8

cotФ=A/O=8/15

hope it helps u!

two rectangular properties share a common side. Lot is 33 feet wide and 42 feet long. The combined area of the lots is 1,848 squ
klio [65]

First, find the area of lot A.

To find the area, multiply the length by the width.

33*42=1,386

Now, subtract the area of lot a from the total area. This will give us the area of lot b.

1,848-1,386=462

The area of lot b is 462 square feet.

Finally, divide the area of lot b (462) by its length to find the width. Since they both share a side, we know that it’s length is 42 feet.

462/42=11

Lot b is 11 feet wide.

Hope this helps!
