Knowledge point: Trigonometry - tangent concept
Multiply the top one by 3 for x, so you can eliminate x and find y
then plug in the y into one of the equations to find x
0.5(2x+2)=-4
Multiply by 2 on both sides
2x+2=-8
Subtract 2 on both sides
2x=-10
Divide by 2 on both sides
x=-5
Answer:
Step-by-step explanation:
Remark
The solution to this is to add the two vertically opposite arcs and take 1/2 of the result to get the intersecting angle of the chords.
Solution
<x = 1/2 (arc measure of 116 + 74)
<x = 1/2 (190)
<x = 95
I don't know what you mean by exponent form, so I'll put it in scientific notation.
8.211 x 10^-1
