i cannot solve it. plz heplme

Answers

There is no solution. (a-a) is zero, and division by zero is disallowed.

when a=a
then a-a=0

so
(a-a)/(a-a)=0/0=2?
false
no solution

What is trigonometry?

The field of mathematics is concerned with the relationships between triangles' sides and angles, as well as the related functions of any angle.

The given data in the problem is;

$\rightarrow \rm (tan((\theta)/(2) )(-5sin\theta)\n\n \rightarrow (sin (\theta)/(2) )/(cos (\theta)/(2)) * - (2 sin n (\theta)/(2) * {cos (\theta)/(2))$

$\rightarrow - (2 sin ^2 (\theta)/(2))\n\n -1+cos \theta$

The given expression is equivalent to (-1 + cosθ).

Hence,option B is correct.

D) A line with 4 tick marks labeled Cat, Dog, Rabbit, and Guinea Pig. Cat has 2 crosses, Dog has 4 crosses, Rabbit has 0 cross, and Guinea Pig has 2 crosses. The line is labeled Number of Pets, and title of graph is Pet Owners.

Answers

Option “A” is correct, because the number of crosses against the pets is equal to its actual quantity given in the question.

Cats = 3 = xxx

Dogs = 5 = xxxxx

Rabbit = 1 = x

Guinea Pigs = 3 = xxx

jenny went to mall with $120 in her wallet. spent $25.65 on a shirt $4.58 on a snack . how much money does she left

Answers

She started off with 120 then spent 25.65 on a shirt then 4.58 on a snack
25.65 and 4.58 are the numbers that you have to add together then subtract from 120.
so 25.65+4.58=30.28
So then you subtract 30.28 from 120 and get 89.72
She has $89.72 left over
Hope I helped :)

$89.77, you subtract both items from her total and that is what she has left in her wallet
