Cot? 2x + cos2x + sin’ 2x = csc? 2x<br> Need help with 40

kkurt [141]

Answer:

$\rule{100mm}{0.1mm}$

$\cot^2(2x)+\cos^2(2x)+\sin^2(2x)=\csc^2(2x)$

$\dfrac{\cos^2(2x)}{\sin^2(2x)} +[(\cos^2(2x)+\sin^2(2x)]=\csc^2(2x)$

$\dfrac{\cos^2(2x)}{\sin^2(2x)} +1=\csc^2(2x)$

$\dfrac{\cos^2(2x)+\sin^2(2x)}{\sin^2(2x)}=\csc^2(2x)$

$\dfrac{1}{sin^2(2x)} =\csc^2(2x)$

$\boxed{\csc^2(2x)=\csc^2(2x)}$ ✔

$\rule{100mm}{0.1mm}$

ramio is 3/10 as tall as the flagpole the flagpole is 5/9 as tall as a nearby tree the tree is 32 2/5 tall how tall is ramiro

Lynna [10]

tree = 32 2/5 = 162/5
flagpole = (5/9)*(162/5)
Ramiro = (3/10)*(5/9)*(162/5)
= 162/30
= 5.4
or as fraction: 5 2/5

Edward earned $1, 491 this month. He spent 1/4 of this monthly salary on rent and 1/20 on utility bills. Which amount is closest

prohojiy [21]

Answer:

$1,043.81

Step-by-step explanation:

$\frac{1}{4}$ ×1,491=372.75

$\frac{1}{20}$ ×1,491=74.55

74.55+372.75=447.19

1,491-447.19= $1,043.81

EG and HJ are parallel lines. Which angles are alternate interior angles?

sertanlavr [38]

Answer:

see below

Step-by-step explanation:

"Alternate" means the angles are on opposite sides of the transversal DK. "Interior" means the angles are between the parallel lines. Here, that means that segment HI will be common to the two angles of interest.

The two pairs of opposite interior angles are ...

∠EFI and ∠JIF
∠GFI and ∠HIF . . . . . matches an answer choice
