Answer:

solution :

in the given figure AB=10.2cm, AC=14cm, AD=DC and AD perpendicular to BC.

now ,

in rt angle tirangle ADC,

angleACD=45 degree, angle DAC=45 degree now,

in triangle ABD,

angle BAD+angleABD+angleADB=180 DEGREE (sum of the sngle of triangle)

angle BAD+75+30=180

angle BAD=180-165 therefore,angle BAD=15

angle BAC =15+45=60

Area of triangle ABC=1/2×AB×AC×SIN 60

=1/2×10.2×14×√3/2

=61.83cm³ ans

A square sheet of paper measures 25 centimeters on each side. What is the length of the diagonal of this paper?

Varvara68 [4.7K]

Answer:

35.36 cm

Step-by-step explanation:

The diagonal of a square will be given by

$D=\sqrt {a^{2}+b^{2}}$

Where a is the length of one side and b is the length of another side. For a square, botj sides are equal hence the diagonal calculations will be as follows

Given that a is 25 then

$D=\sqrt {25^{2}+25^{2}}$

D=35.3553390593274

Rounding off the nearest two decimal place

D=35.36 cm
