i need help with this too

Answer 2

first question answer is D

Answer 3

how did you get that?

Answer 4

the slant height height you use Pythagoras theorem

\[a ^{2}+b ^{2}=c ^{2}\]

Answer 5

\[l= \sqrt{8^{2}+5^{2}}=\sqrt{89}\]

Answer 6

qn 2 :
ABC = 0.5*(15+6)*8
ADC= 0.5*(15+6)*8 , add them together to get your answer

Answer 7

the second answer is C 168

Answer 8

where did you get that equation to solve problem 2?

Answer 10

calculate base XT => 12 cos60
calculate height WX-> 12 sin60
calculate the area of triangle WXT => 0.5 * 12cos60* 12sin60
