Answer:
X=-1.1 repeated
Step-by-step explanation:
9x - 1= -11
+1= +1
9x = -10
Divide by 9 on both sides
X = -1.1 repeating
External angle is equal to the sum of the other 2 internal angles
2x=x-5+63
minus x from both sides
x=-5+63
x=58
x=58°
Answer:
option (A)
central angle = 0.375 rad
Step-by-step explanation:
Given in the question,
radius of the circle = 8 inches
arc of the circle = 3 inches
To find,
measure of a central angle
Central angles are subtended by an arc between those two points.
Formula to use:
<h3> s = (r) (θ)</h3>
<em>where r = radius </em>
<em> s = arc length </em>
<em> θ = angle in radians</em>
<em />
Plug in the values in the equation
<h3>3 = (8) (θ)</h3><h3>θ = 3/8 </h3><h3>0.375 rad</h3>
3x - 45 = 2x + 5
3x - 2x = 5 + 45
x = 50
4y - 1 + 2x + 5 = 180
4y + 2(50) + 4 = 180
4y = 180 - 4 - 100 = 76
y = 76/4 = 19.
y = 19
