a: góc đối đỉnh với góc yOv là góc uOz

b: góc uOz=góc yOv

mà góc yOv=110 độ

nên góc uOz=110 độ

c; Ot là phân giác của góc uOz

=>góc uOt=1/2*góc uOz

=>x=1/2*110=55 độ

 \(=>Qthu1=0,2.340000=68000J\)

\(=>Qthu2=2100.0,2.20=8400J\)

\(=>Qtoa=2.4200.25=210000J\)

\(=>Qthu1+Qthu2< Qtoa\)=>đá nóng chảy hoàn toàn

\(=>0,2.2100.20+0,2.340000+0,2.4200.tcb=2.4200\left(25-tcb\right)\)

\(=>tcb=14,5^oC\)
