Use Pythagorean's, in figure 1: t^2+12^2=13^2. t=\sqrt(13^2-12^2)=\sqrt(25)=5.
In figure 2: 6^2+9^2=x^2. x=\sqrt(36+81)=\sqrt(117)=3*\sqrt(13).
Answer:
7(2x + 12) = -28
14x + 84 = -28
14x + 0 = -112
14x/14 -112/14
x = -8
Step-by-step explanation:
hope this helps :)
C, Change them to y=mx+b
B, Plug in numbers after converting to y=mx+b
D, Only the y-intercept changes
A, Plug in given coordinates
Answer:
90°
Step-by-step explanation:
The sum of the arcs around the circle is ...
2x +4x +4x +2x = 360°
x = 360°/12 = 30°
The numbered angle is the average of the measures of the intercepted arcs, so is ...
(4x +2x)/2 = 3x = 3(30°) = 90°
The numbered angle is 90°.
