A picture would help. If I've reconstructed it correctly, it appears that RSU is a 90 degree angle and UST is a 45. That means that 1/2(7x - 10) = 3x + 15 x = 40
Supplementary angles, when added together, equal 180 degrees. If we let the smaller angle equal X we know that X + (2X + 60) = 180 3X+60=180 3X=120 X=40 The small angle is 40 degrees. The larger angle is 2(40)+60=140 degrees.
Let x equal the first angle.let 4x= the second anglelet 3x+10x+4x+3x+10=180 The sum of the interior angle measures of a triangle is 180 degrees.8x+10=180 combine like terms8x=170 addition(subtraction) property of equalityx=21.25 degrees
Let the larger angle be 2x and the smaller angle be x: 2x+x = 93 3x = 93 Divide both sides by 3 to find the value of x: x = 31 Therefore the larger angle is 62 degrees.
to find sin 35 here we take the angle = x=15 then 3x=45 , 4x=60 then 4x-3x=60-45 then by putting sin on rhs we will get cos 35 and sin 35 hope it helped you
