4(8x + 56) = 20
= 32x + 224 = 20
The complete question in the attached figure
we know that
sin40° = opposite side / hypotenuse
opposite side =AC
hypotenuse = AB-------> 10 in
so
sin 40=AC/AB---------> AC=AB*sin 40-------> AC=10*sin 40
the answer is
AC=10*sin 40
Answer:
B
Step-by-step explanation:
Because when you do the math and you solve the triangle you would get the answer
Answer:
..
Step-by-step explanation:
no the correct point would be (7,12)
7x1=7
7+5=12
X+3y=7
x-3y=1
add them together
x+3y=7
<u>x-3y=1 +
</u>2x+0y=8
2x=8
divide 2
x=4
subsitute
x+3y=7
4+3y=7
subtract 4
3y=3
divid 3
y=1
x=4
y=1
answer is A
