Answer:

Step-by-step explanation:
We are given a triangle
whose sides are
a=12
b=8
c=13
Since, c is largest among them
So, angle C must be largest angle
we can find angle C
we can use law of cosine formula

now, we can plug values


now, we can find angle
we get

Answer:
x₁ = 6 and x₂ = 8
Step-by-step explanation:
See the picture below
Y=36
it basically says y=(9-3)^2
which is y=6^2
which is then y=36
It's a glitch I believe (screenshot and contact your teacher)
Get them to have a common denominator. 100 is the common denominator, so change 7/10 and 3/5 to have a denominator of 100. 7/10=70/100 and 3/5=60/100. So from least to greatest it will go 8/100, 3/5, 7/10.
