Heyy

Step-by-step explanation:

△ABC is a right angled triangle and right angle at B

sinA=

, cosA=

⟹sinA+cosA=

BC+AB

[We know that sum of two sides of a triangle is greater than the third side]

⟹sinA+cosA>

Hence, sinA+cosA>1

Write an equation with the two points: (5,-2) and (3,4)

eimsori [14]

Answer:

$y=-3x-17$

Step-by-step explanation:

To find out the m(slope) of the equation use the formula:

$\frac{y_2-y_1}{x_2-x_1}$ .

Substitute the values:

$\frac{4--2}{3-5}$

Combine the values:

$\frac{6}{-2}$

Find the value of the fraction:

$-3$

M is -3.

The equation so far is $y=-3x+b$

To find the y intercept, substitute one pair of coordinates into the equation and solve for b:

$y=-3x+b\\-2=3*5+b\\-2=15+b\\-17=b$ .

We see that b =-17 so the full equation would be:

$y=-3x-17$ .
