No because 1233/9 does not produce a whole number therefore 9 is not a factor of 1233

Help me solve for the right triangle
AleksAgata [21]

Answers:

B = 50

a = 10.9

c = 17.0

================================================

Explanation:

This is a right triangle, so the acute angles are complementary, meaning they add to 90

B+40 = 90

B+40-40 = 90-40

B = 50

Also, because this is a right triangle, we can use trig ratios to compute the missing sides

tan(angle) = opposite/adjacent

tan(40) = a/13

a = 13*tan(40)

a = 10.908

a = 10.9

cos(angle) = adjacent/hypotenuse

cos(40) = 13/c

c*cos(40) = 13

c = 13/cos(40)

c = 17.0

note: make sure your calculator is in degree mode

What is the solution to the inequality below?
dimaraw [331]
  • 12 + x ≥ 3 (x - 6)
  • or, 12 + x ≥ 3x - 18
  • or, 12 + 18 ≥ 3x - x
  • or, 30 ≥ 2x
  • or, 30/2 ≥ x
  • or, 15 ≥ x
  • or, x ≤ 15

<u>Answer</u><u>:</u>

<em><u>x </u></em><em><u>≤</u></em><em><u> </u></em><em><u>1</u></em><em><u>5</u></em>

Find an equation for the line perpendicular to the line −4x+3y=−2having the same y-intercept as −7x−7y=6
SCORPION-xisa [38]

First we need to find slope of given line −4x+3y=−2

So convert it into slope intercept form y=mx+b

−4x+3y=−2

3y=4x−2

y=4/3x−2/3

Comparing above equation with y=mx+b gives m=4/3

Hence slope of given line is 4/3.

<em>We need slope of perpendicular line which is always "negative reciprocal of given slope"</em>.

Negative of 4/3 is -4/3.

taking reciprocal gives -3/4

Hence slope of required perpendicular line is m=-3/4

-------

Now we need to find y-intercept of −7x−7y=6

y-intercept is always the y-value when x=0 so let's plug x=0 into −7x−7y=6

−7(0)−7y=6

0−7y=6

−7y=6

y=-6/7

y-intercept is also called "b" in y=mx+b

hence b=-6/7

-----

Now we know that slope of perpendicular line is m=-3/4 and y-intercept b=-6/7

so plug both into formula y=mx+b

We get Final answer is y=-\frac{3}{4}x-\frac{6}{7}
