If the legs of an isosceles right triangle have a length of 15√2 ft, the hypotenuse will have a length of _____feet.

Soloha48 [4]

we know that

An isosceles triangle has two equal sides and two equal angles

If the isosceles triangle is a right triangle

then

The measure of the angles are $45\°- 90\°- 45\°$

$cos (45\°)=\frac{\sqrt{2}}{2}$

$cos (45\°)=\frac{leg}{hypotenuse}$

$\frac{leg}{hypotenuse}=\frac{\sqrt{2}}{2}$

we have

$leg=15\sqrt{2}\ ft$

Substitute and solve for the hypotenuse

$\frac{15\sqrt{2}}{hypotenuse}=\frac{\sqrt{2}}{2}\\ \\hypotenuse=2*15 \\ \\ hypotenuse=30\ ft$

therefore

<u>the answer is</u>

$30\ feet$

(iii) A relation between a and b such that point (a,b) isequidistant from the points (8,3) and (2,7)

RUDIKE [14]

Answer:

7.21 units

Step-by-step explanation:

GIven data

Point 1= (8,3)

x1= 8

y1= 3

Point 2= (2,7)

x2= 2

y2= 7

The expression for the distance between two points is given as

d=√((x_2-x_1)²+(y_2-y_1)²)

substitute

d=√((2-8)²+(7-3)²)

d=√((-6)²+(4)²)

d=√36+16

d=√52

d= 7.21

Hence the distance between the points is 7.21 units
