The angles of a triangle will always add up to be 180 degrees total.
x + 82 + x + 82 + 40 = 180
2x + 164 + 40 = 180
2x + 204 = 180
Subtract 204 from both sides.
Think of it as “180 + (-204)”
2x = -24
Divide each side by 2.
x = -12
Answer: x = -12
Answer:
123.948 km²
Step-by-step explanation:
We can use the equation: <em>AΔ = 1/2*ab*sinθ</em>, where a and b are the lengths of the sides next to the known angle, and θ is the angle itself.
Plugging in the numbers we know, we get: <em>AΔ = 1/2*22*24*sin(28°)</em>
Simplify: <em>AΔ = 264*.4695</em> (0.4695 is approximately sin(28°))
Simplify: 123.948 km²
Answer: Arithmetic sequence
Step-by-step explanation:
The pattern in the sequence is n = n-1 + 6. Since n is increasing through addition with each term, this sequence is arithmetic.
Answer:
bc thast not a number in the quation therfore you wouldnt use it
Step-by-step explanation:
Assuming this is a rectangular prism, here are the formulas for the volume and surface area.
V=l×w×h
SA=lw+lw+lh+lh+wh+wh
I didn't want to give the answer away, but I wanted to head you in the right direction. Hope this helped!
