Answer:
5).40°
6).hypotenuse
7).24cm
Step-by-step explanation:
5)
let the angles are 2x ,3x and 4x
we know that sum of all angle of a triangle=180°
A/q,
=> 2x+3x+4x=180
=> 9x=180
=>. x=20°
so smallest angle=2x
=2*20°
=40°
6)
hypotenuse is the longest side because it is the sum of square of both side
by Pythagoras theorem
hypotenuse²=base²+height²
7)
AB=7cm
AC=25cm
from Pythagoras theorem,
AC²=AB²+BC²
=> 25²=7²+BC²
=> BC²=25²-7²
=> BC²=625-49
=> BC²=576
=> BC=√576
so,BC=24cm
follow back yrr
mark it plzzz
