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°
Answer:
540 middle school students.
Step-by-step explanation:
54/75 equals x/750. 75 times 10 equals 750 so 54 times 10 equals 540 middle school students
Answer:
976 square cm
Step-by-step explanation:
Area of one 2d triangle face: (24*14)/2=168 square cm
Area of both 2d triangles faces: 168 + 168 =336 square cm
Area of one side: 25*10=250 square cm
Area of both sides: 250+250=500
Area of base: 14*10=140 (since it's a triangular prism, there's only one base)
Surface Area: 336+500+140=976 square cm
Hope this helps! :)
Yes, I believe that is correct.
