bài nào vậy bn:?

a: MNPQ là hình bình hành

=>MQ//NP

=>MQ//IP

Xét tứ giác MIPQ có IP//MQ

nên MIPQ là hình thang

b: ΔMNP vuông cân tại N

=>MN=NP và \(\widehat{MNP}=90^0\)

Hình bình hành MNPQ có \(\widehat{MNP}=90^0\)

nên MNPQ là hình chữ nhật

=>\(\widehat{Q}=\widehat{P}=90^0\)

Xét ΔMNI vuông tại N có \(sinNMI=\dfrac{NI}{MN}=\dfrac{2}{3}\)

nên \(\widehat{NMI}\simeq42^0\)

\(\widehat{NMI}+\widehat{QMI}=\widehat{NMQ}=90^0\)

=>\(\widehat{QMI}+42^0=90^0\)

=>\(\widehat{QMI}=48^0\)

IP//MQ

=>\(\widehat{QMI}+\widehat{MIP}=180^0\)(hai góc trong cùng phía)

=>\(\widehat{MIP}+48^0=180^0\)

=>\(\widehat{MIP}=132^0\)

x : 4 + x = 3,75

\(x\)x\(\frac{1}{4}\) + \(x=3,75\)

\(x\)x\(\left(\frac{1}{4}+1\right)=\frac{375}{100}\)

\(x\)x\(\frac{5}{4}=\frac{15}{4}\)

\(x=\frac{15}{4}:\frac{5}{4}\)

\(x=\frac{15}{4}\)x\(\frac{4}{5}\)

\(x=3\)

\(\frac{x}{4}+x=3.75\)

\(x\left(\frac{1}{4}+1\right)=\frac{15}{4}\)

\(x\cdot\frac{5}{4}=\frac{15}{4}\)

\(x=\frac{15}{4}:\frac{5}{4}=3\)

x :4 +x=3,75

=>0,25x+x=3,75

=>125x=3,75

=>x=3,75:1,25

=>x=3

easy

x(4+1) : x(x+1)=0

(x:x) 5(x+1)=0

5x+5=0

5x=-5

x=-1
