Answer:
option 4
Step-by-step explanation:
using the sine/ cosine ratios in the right triangle and the exact values
cos30° =
, sin30° =
, then
cos30° =
=
=
( cross- multiply )
2x = 20
×
= 20 × 3 = 60 ( divide both sides by 2 )
x = 30
and
sin30° =
=
=
( cross- multiply )
2y = 20
( divide both sides by 2 )
y = 10
Make it improper.
-4×25+4=96
96/25
make the bottom number 100
96× 4 25×4
384/100
simplify 3 and 84/100
3.84 is your answer
A = (1/2) b* h
OR
A = (b*h)/2
A = (8* 2)/2
A = 16/2
A = 8 yd^2
Letter D
