Find a solution for the equation. assume that all angles are acute angles. sin( 2β + 10°) = cos( 3β - 25°)

1 answer:

5 0

The sine of one acute angle is equal to the cosine of another when their sum is 90°.
.. (2β +10°) +(3β -25°) = 90°
.. 5β -15° = 90°
.. 5β = 105°
.. β = 21°

Then your equation becomes
.. sin(52°) = cos(38°)

6/7x - 2/5y + 5/7(y+x)

makvit [3.9K]

Answer:

$\frac{6}{7} x - \frac{2}{5} y + \frac{5}{7} (y + x) \\ = ( \frac{6}{7} + \frac{5}{7} )x + ( \frac{5}{7} - \frac{2}{5} )y \\ = \frac{11}{7} x + \frac{15}{35} y \\ = \frac{11}{7} x + \frac{3}{7} y \\ = \frac{1}{7} (11x + 3y)$

The sum of two numbers is 981. One of the numbers is 703. What is the other number?

victus00 [196]

Answer:

Other number is 278.

Step-by-step explanation:

Given that

a + b = 981

One of the numbers = 703

We assume that it is a ; So

a = 703

Other number = b = ?

Put value of a in a + b

a + b = 981

703 + b = 981

b = 278
