the inside of quadrilateral is always 360°.So add 75°,90° and 75° and then subyaract from360°.
x+75°+75°+90°=360
×+240°=360°
x=360°-240°
x=120°
The length I think is 15 and the width I think is 19
Answer:
The second one is the right one
4.33
<span>4.1 × 10^13 / 9.46 × 10^12= 4.33</span>
Do 12-5 then 6.4 then 2.2 then whatever answer you get for 12-5 multiply it by the answer you get for 6.4 then subtract whatever answer you get for 2.2 hope this helps!
