beks73 [17]

Answer:

h=9cm

P=(x+5)cm

b=(x-3)cm

by the Pythagoras theorem,

h^2=p^2+b^2

9^2=(x+5)^2+(x-3)^2

81=x^2+10x+25+x^2-6x+9

81=2x^2+4x+34

Nataly_w [17]

Answer:

n = 5

Step-by-step explanation:

\because m \angle \: 3 + m \angle \: 4 = 180 \degree..(supplementary \:  \angle s) \\  \therefore \: 9n + 24n + 15 = 180 \\  \therefore \:  33n = 180 - 15 \\ \therefore \: 33n = 165 \\ n =  \frac{165}{33}  \\  \huge \red{ \boxed{\therefore \: n = 5}}
