DUED BY 10. Does anyone know how to do number 6 please help me out bro, (it’s geometry btw)

6 and 7

Step-by-step explanation:

By Pythagoras Theorem,

Take the bigger side 18m in Q-6 then put it in Pythagoras formula:-

h=18m

p=10m

b=13m

Now,

h^2 = p^2 + b^2

(18)^2 = (13)^2 + (10)^2

324 = 169 + 100

324 ≠269

Hence, Proved

Similarly with 7.

last option: rhombus or kite

step-by-step explanation:

a kite and rhombus have the same shape. as we don't have any specific formula for the calculation of area of kite. the diagonals are used to calculate the area of a kite or rhombus.

the formula for area of rhombus is given by:

here, d_1 is the first diagonal and d_2 is the second diagonal.

so,

last option is the correct answer ..

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
