Answer:
Sin 90 = 1/1 = 1
Use trigonometry formula and a triangle with lengths of 1
7x w x 13=546
(7x13)*w= 546
91w=546
91w/91= 546/91
w= 6
the width is 6cm
you have to use cross-multiplication in order to find out the answer to this question.
Step-by-step explanation:
9/12 times 2/3
slope=<u>y</u><u>2</u><u> </u><u>-</u><u> </u><u>y</u><u>1</u>
x2 - x1
= <u>-</u><u>1</u><u> </u><u>-</u><u> </u><u>-</u><u>3</u>
-7 - -9
= <u>-</u><u>2</u>
-2
= 1
I think the answer is D
