If m L=65, then m LJK=___ ????? PLS HELP ASAP
aleksandr82 [10.1K]

Answer:

50 degrees

Step-by-step explanation:

If angle L = 65 then the top angle for the triangle LMJ has to be 25 degrees as M is a right angle (or at least has to be for this problem to be possible)

the math to figure it out is 90+65+x=180 <-- due to triangles are 180 degrees inside which simplifies to 25 after that you just have to at 25 to itself 25+25 to get 50 which is the angle of J

Volume and Surface Area<br><br> Math help 100 points
kondor19780726 [428]
Part 1) we have that
volume smaller solid=512 cm³
volume larger solid=2197 cm³

we know that
volume larger solid=[scale factor]³*volume smaller solid
scale factor=∛[volume larger solid/volume smaller solid]
scale factor=∛[2197/512]-----> scale factor=1.625


Part 2) 
the ratio of the surface areas is equal to [scale factor]²
1.625²-------> 2.64

Part 3)
surface area smaller solid=960 cm²
then
surface area larger solid=scale factor²*surface area smaller solid
surface area larger solid=[1.625]²*960-----> 2535 cm²
 surface area larger solid is  2535 cm²
