It would be 25°. also, the interior angles of a triangle always add up to 180 so use that to find answers for other questions like this
Lets call the number 'n'
plus means addition
is means the equal sign
so that as an expression would be
n+4=7
Answer:
6/5 or 1.2, they're the same value
Step-by-step explanation:
When it says "rate of change", it's really just asking for the slope. If you don't know what the slope is, essentially how much the y-value increases by whenever x increases by 1. This can be formally defined using the equation: which is essentially . The subtraction is finding the difference between the two numbers to see how much it's changed by. Btw the order doesn't matter, I could plug in (-3, -2) as (x2, y2) or I could plug it in as (x1, y1) as long as I make sure to input it in correctly. In this example I'll just say (-3, -2) = (x1, y1) and (2, 4) = (x2, y2). Plugging these values into the equation gives you: that's the rate of change
Answer:
A = 27.7
Step-by-step explanation:
Knowing that an equilateral triangle has 3 equal side lengths, we can create our area and perimeter equations! x will be one of the side lengths
- A = (1/2)(b*h)
- all angles are 60
- Using angles: sin(60) =
- A =
P = 3x = 24
x = 8
A =
A = 27.7
