Apa maksud dari 2:1 cuka dan air ?
Answer (3)
10x+2x+13=145 angle of WIJ and HIW is equal to 145 degrees 12x+13=145 12x=132 x=11 angle of WIJ is 10x angle of HIW is 2x+13 to find angle of HIW, you plug in x=11 into 2x+13 and the answer and angle of HIW is 35 degrees.
The measure of angle HIW is 35 degrees, calculated using the equation based on the relationship between the angles WIJ and HIW. By solving for x, we found that x equals 11, which we then substituted back into the equation for HIW. This led us to the final measure of angle HIW as 35 degrees.

itu menandakan komposisi dalam larutannya,contoh,kita punya 750ml larutan cuka 2:1maka cukanya ada 500mlairnya ada 250mlkl 100ml?caranya tinggal pake perbandingan,cuka = 2/3 x 100ml =66,667 mL air = 1/3 x 100ml =33,333 mL
