Answer:
I'm not sure but I did do it on a calculator so 1.515-1.56= -0.045

<u>Given expression is </u>

can be rewritten as

We know,

And

So, using this identity, we


can be further rewritten as





<u>Hence, </u>

Answer:
y=-3x-8
Step-by-step explanation:
y=1/3x+9
slope is 1/3
perpendicular slope = m
(m)(1/3) = -1
m = -3
Point slope form
(y+2)/(x+2)=-3
y+2=-3x-6
y=-3x-8
The answer is A because if you multiply you’ll get 70°
Answer:
acute
Step-by-step explanation:
Here are some helpful rules that will help you out in the future with these questions.
If...
a^2 + b^2 = c^2 its a right triangle
a^2 + b^2 < c^2 its obtuse
a^2 + b^2 > c^2 its acute
so...
Since 6+8>10
its acute
