The points lie on the line, I believe, since they're part of it.
Answer:
17
Step-by-step explanation:
∠C is common in both triangles
equate them
∠C = 180- (x + 100) = 180 - ( 4x + 49)
x + 100 = 4x + 49
100 - 49 = 3x
51 = 3x
x = 51/3 = 17
Answer:
12.4 did this before
Step-by-step explanation:
To do this make x and y equal 0, y-intercept is at x=0, and x-intercept is at y=0:
x-intercept:
2x+7(0) = -14
2x = -14
x = -7
y-intercept:
2(0) + 7y = -14
7y = -14
y = -2
Answer:
Pretty sure its 7.5 units²
Step-by-step explanation:
5·3=15÷2=7.5
Doing area with triangles is kind of the same as rectangle, just do base × height. But then divide it by two.
For example: base=3, height=7. With rectangles it would be 21 units².
But with triangles it would be 3·7=21 divided by 2, it would be 10.5 units²
