Okay thank u🙏🙏

Can u help me with another question

[knotty falcon]

this should be in degrees

alternately you can multiply your answer by pi/180 to convert from radians to degrees

[knotty falcon]

i can try post

I dont think its trigo tho

[knotty falcon]

angles of a right angle other than 90 are complementary meaning their sum is 90 you can solve for x by adding them and equating to 90

or you can use the angle sum property of triangles

sum of all angles of a triangle equal 180

Idk if I got it right.. I got 12.714

[knotty falcon]

,calc 91/7

[barren dome]

13

[knotty falcon]

[knotty falcon]

it is 3x-1

[shut path]

Y° = arctan (7.5/12.8)

[shut path]

Result is 30.367°
