You can use a plot diagram to plot the points and if they all go straight through the origin then it is proportional :)
Answer:
Step-by-step explanation:
sum of angles of triangle=180
90+50+B=180
B=180-140
<h2>B=40</h2>
sin50= 0pp/hyp
sin50= 24/c
c=24/sin 50
<h2>c=31.3</h2>
sin B= opp / hyp
sin 40 = b/c
<h2>b= 20.1</h2>
Answer:
Hello! answer: x = 19
Step-by-step explanation:
This is a supplementary angle! So it will add up to 180 degrees 180 - 123 = 57 so we know something multiplied by 3 will equal 57 and 19 × 3 = 57 so x = 19 Hope this is a good explanation!
