Answer:
angle 3 = 60
Step-by-step explanation:
60-60-60 triangle rule
this triangle has 2 60 degree angles so it fits this rule
equilateral traingle
<u>or </u>
a triangle has a total of 180 degrees
so:
180-(60+60)
180-120
60
Answer:
x=10
Step-by-step explanation:
1/2x+4=9
subtract 4 from both sides
1/2x=5
multiply both sides by 2 to get x by itself
x=10
Answer:
The x-intercept is (-2,0)
The y-intercept is (0,3)
Step-by-step explanation:
An x-intercept is the point when the graph crosses the x-axis. In other words, the y-coordinate of the x-intercept is 0 (since it lays on the x-axis). In other words, to solve for the x-intercept(s), plug in 0 for y and solve for x:

So, the x-intercept is (-2,0).
Likewise, the y-intercept is the point when the graph crosses the y-axis. Because it's on the y-axis, the x-coordinate value would be 0. Thus, to find the y-intercept, plug in 0 for x and solve for y:

Thus, the y-intercept is (0,3).
The answer would be B, since the other two just have to equal 100.
