Suppose a triangle has to size of lint 42 and 35 and the angles between these 2 sides is 120 which equated should you solve to f

Brilliant_brown [7]

Answer:

$7\sqrt{91}\ units$ or $66.78\ units$

Step-by-step explanation:

we know that

Applying the law of cosines

$c^{2}=a^{2}+b^{2}-2abcos(C)$

In this problem we have

$a=42\ units, b=35\ units, C=120\°$

c is the length of the third side

Substitute

$c^{2}=42^{2}+35^{2}-2(42)(35)cos(120\°)$

$c^{2}=1,764+1,225-2,940cos(120\°)$

$c^{2}=4,459$

$c=\sqrt{4,459}\ units$

$c=7\sqrt{91}\ units$ or $c=66.78\ units$

Find an equation of the line that is perpendicular to 9x + 5y = - 1. Write your answer in the form y = mx + b.

Alchen [17]

Answer:

Step-by-step explanation:

move x to the right making the equation 5y=-9x-1 then divide both sides by 5 to get y= -9/5x-1/5. the slope of a perpendicular line is the opposite reciprocal of the slope from the og eq. so the slope of the new line is 5/9x and the y-intercept stays the same so the equation should be y=5/9x-1/5
