Answer:
x = 0.5 to the nearest 1/10.
Step-by-step explanation:
3^-x = x^3 + x
y = x^3 - 3^-x + x = 0
Using a graphing calculator to draw the graph of the above:
The graph crosses the x-axis at x = 0.4798
That’s a obtuse angle I’m pretty sure.
Answer:
the area of a triangle = 19 km²
Step-by-step explanation:
area of a triangle = 1/2 b h
where b = 5km
h = 7.6 km
plugin values into the formula:
A = 1/2 (5) 7.6
A = 19 km²
therefore,
the area of a triangle = 19 km²
This is true because a triangle must add up to 180 degrees and we are given 2 angles per triangle, one is 90. 52 + 38 = 90 and 90+90=180
