Answer:
A. x=√60
Step-by-step explanation:
Divide 4 in half because you are solving half of an isosceles triangle
You formula is x²+2²=8²
Square root what you can: x²+4=64
Isolate the variable: x²=60
Square root both sides, x=√60
Answer:
197
Step-by-step explanation:
Assuming the question is asking for the sum of 14 squared and 1 cubed, 14 squared is 196 and 1 cubed is 1. Adding these together is 196+1 which gives 197.
I am pretty sure you can only make one.
If two sides are known, and one of the angles, then the other bits can be deduced and are fixed.
Answer:
y=-2x+10
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(8-(-10))/(1-10)
m=(8+10)/-9
m=18/-9
m=-2
------------------
y-y1=m(x-x1)
y-(-10)=-2(x-10)
y+10=-2x+20
y=-2x+20-10
y=-2x+10
Answer:
not a right triangle
Step-by-step explanation:
We can use the Pythagorean theorem to see if it is a right triangle
a^2 + b^2 = c^2
15^2 + 12^2 = 21^2
225 + 144 = 441
369 = 441
This is not true so it is not a right triangle
