Since the sum of the angles in a triangle has to equal 180, you know that angle BCA is 180 - (70+40), or 70°. Angle BCA is supplementary to x, which means together they add up to 180. Therefore, x = 180 - 70 = 110°.
<span>In this lesson, you learned about </span>linear and nonlinear functions<span>. The equation of a </span>linear function<span> has no exponents higher than 1, and the graph of a </span>linear function<span> is a straight line. The equation of a </span>nonlinear function<span> has at least one exponent higher than 1, and the graph of a </span>nonlinear function<span> is a curved line. hope that helped</span>

Step-by-step explanation:
If you would like to convert meters to kilometers, you can calculate this using the following step:
1 meter = 0.001 kilometers
1900 m = 1900 * 0.001 km = 1.9 km
If the tunnel is about 1900 m = 1.9 km long, then this is a little less than 2 km, because 1.9 km < 2 km.
