Which of the following must be true?

cos 38° = 17/c

Step-by-step explanation:

in the triangle shown

the sum of angles in a triangle is 180°

its a right angle triangle meaning one of the angles is 90°

the other part is 52°

the third part is described as x

90° + 52° + x = 180° ( sum of angles )

142° + x = 180°

x = 180 - 142 = 38°

cos 38° = adjacent/hypothenus = 17/c

cos 38° = 17/c

i belive those are the ones that are under 90 degreese.

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
