Find the area of the triangle below 5.4 m 9 m 4.5 m 7.5 m​

d. 145*2 is 290 than the total angle is 360 then minus 290 then divide by two

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.

question

given the diagram below, what is md?

the sum of the interior angles is 360°

take away from 360 the sum of the knows angles and you will have the angle d.

360 - 108 - 108 - 72 = 72°
