Triss [41]
To find the measure of the third angle you should keep in mind the following:
 The sum of the three interior angles of a triangle is 180 °.
 We have then

Given four functions, which one will have the smallest y-intercept?
Natalka [10]
F(x) function has a starting value of $6.00 and increases from there.So the y-intercept is 6.

g(x) function shows in the table that when x = 0, y = 6. This is the y-intercept.

h(x) shows on the graph that the y-intercept is  4.

j(x) is an exponential growth function, a * b^x where a is the y-intercept.
y = 10^ x^x has a y-intercept at 10. 

The smallest y-intercept is function h(x).
