heres the work sheet. I need some help with it i dont get any type of grade for it at all but teacher told me to do it.

Answer 3

so which parts are the problems..?

Answer 4

ok um one second ill tell you

Answer 5

9, 11, 12, 13, 14, 19

Answer 6

ok... 11 and 12...

express the corresponding sides in a ratio

1st shape : 2nd shape
11. 5 : 3 the ratio can't be simplified so its 5:3 or 5/3

tell me what you think about 12...

1st shape : 2nd shape

Answer 7

9:12 or else 3:4
or 3/4

Answer 8

thats it... well done

ok... looking at 14

you need to find the angle size... so let the base angles of the isosceles triangle be x.

Answer 9

oops thats 13.... not 14

Answer 10

its ok lol

Answer 11

x=36?

Answer 12

great so the base angles are 36 and the angle at the top is 108

so use the trig formula for area of a triangle

\[A = \frac{1}{2} \times a \times b \times \sin(C)\]

in your question a = 14, b = 14 and C = 108

hope that helps

Answer 13

question 14 uses the same formula to find the area of the triangle

a = 3, b = 4 and C = 52

Answer 14

10480? thats what my calculator got

Answer 15

ummm

\[A = \frac{1}{2} \times 14 \times 14 \times \sin(108)\]

Answer 16
