Answer:
x = 6
Step-by-step explanation:
A = 1/2bh
36 = 1/2(12)(x)
x = 6
Answer:
Cos 74°= Sin 16°
Sin 20°= Cos 70°
Sin A°=Cos (90°- A°)
Step-by-step explanation:
This is because the three pairs are complementary i.e they add up to 90° and in trigonometric ratios, complementary ratios are equal.
Answer:
B
Step-by-step explanation:
we are given a equation of a line
we want to figure out the equation of the perpendicular line passes through the <u>(</u><u>6</u><u>,</u><u>5</u><u>)</u><u> </u>points
in order to do so
recall that,

we got from our given equation that m=2
because equation of a line is y=mx+b
thus

remember that, when we want to figure out perpendicular line or parallel line we should the formula given by

since we got our perpendicular m is -½,
and
, substitute

to get the perpendicular equation you should simplify the above equation to y=mx+b form
distribute -½:

add 5 to both sides:

hence,
our answer choice is B

Answer:
(3, 1)
Step-by-step explanation:
x+5y=8
-x+2y=-1
-------------
7y=7
y=7/7=1
x+5(1)=8
x+5=8
x=8-5=3
Answer: x=3, y=1.
