Answer 1

Step-by-step explanation:

Answer of C

Step by Step

to find CB and CDandBD

lets start,

By Phythagoras theorem,

AC^2= AB^2+BC^2

(10^2)=(6^2)+BC^2

100=36+BC^2

therefore, BC^2=100 -- 36

BC^2=64

BC=8------------- Taking Square root

By Phythagoras theorem,

In Δ CDF

CF^2=FD^2+CD^2

13^2= 12^2+ CD^2

169=144+CD^2

therefore, CD^2=169 -144

CD^2=25

therefore, CD=5------------Taking square root

Answer 2

Answer:

(a)

• 2(x-5) +3(x-2) = 8+7(x-4)
• 2x - 10+3x -6 = 8+ 7x -28
• 2x +3x -10 +6 = -28 +8+ 7x
• 5x -4 = -20 + 7x
• -4 + 20 = 7x -5x
• 16= 2x
• 16 = x

2

• $8 \: ans.$

Step-by-step explanation:

(b)

They both are congruent by RHS (right angle, hypotenuse and side {either base or perpendicular}).

1.

$< a = < d$

2.

BP= CP

3.

AP= DC= 5cm

Hence, They are congruent by RHS rule.

(c)
