Write the 5th and 8th terms of an AP whose 10th term is 43 and common difference is 4.​

t5=23     t8=35

Step-by-step explanation:

t5=?

t8=?

t10=43

d=4

tn=a+(n-1)d

t10=a+(10-1)4

43= a+(9)4

43=a+ 36

a=7

t5=7+(4)4

t5=7+16

t5=23

t8=7+(7)4

t8=7+28

t8=35

#15. square

step-by-step explanation:

because quadrilatural (idk how to spell it) means somthing that is not 3d or like, equal sides (or somthing like that   you know what i meanz)

hope this halps!

bai!

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
