Consider △abc. what are the angles that make the trigonometric statements true? sin(_a_) = cos(b) sin(b) = cos(_a_)(the answers are in the question i posted lol)

Answers:

∠A=45° & ∠B=45°

Step-by-step explanation:

In triangle ABC, all angles are less than 180° but their sum is 180°

For the trigonometric statements  

sin(A)=cos(B)

sin(B)=cos(A)

These are true when these angles that are A and B are equal and on these angles the sin and cos value must be same.

Hence, both angles are of 45°

The angles that make the trigonometric statements true are

Trignometry helpd in the determination of the angle of the triangle with the sides of the triangle.  To calculate the angle, the sum of the traingle is known to be 180.

Given :

Triangle ABC.

Solution :

If  

and

than both angle A and angle B are equal and

Therefore, the angles that make the trigonometric statements true are

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w

answer: 60%

explanation:

÷

= 60%
