Step-by-step explanation:
<em>Answer:</em>
<em>C = 12.88</em>
<em>Step-by-step explanation:</em>
<em>If the radius of the circle is 4 cm, then the diameter of the circle is 4 cm x 2, or 8 cm. If you know the circumference of the circle, divide it by </em><em>π</em><em> to get the diameter.</em>
<em>C = π d = π · 4.1 = </em><em>12.88</em><em>053cm </em>
Glad to help ya!!
Answers:
- angle1 = 156 degrees
- angle2 = 24 degrees
=======================================================
Explanation:
The two angles form a straight line, which is 180 degrees
Add up the angle expressions and set the sum equal to 180.
(angle1) + (angle2) = 180
(4x) + (x-15) = 180
(4x+x)-15 = 180
5x-15 = 180
5x = 180+15
5x = 195
x = 195/5
x = 39
We use that x value to find each missing angle
- angle1 = 4x = 4*39 = 156 degrees
- angle2 = x-15 = 39-15 = 24 degrees
Then notice how angle1+angle2 = 156+24 = 180 to verify the answer.
Side note: Angles that add to 180 are considered supplementary.
Answer:
3x+85= 21
or, 3x= 85- 21
or, 3x= 64
or,x= 64/3
;. x= 21.3
Step-by-step explanation:
the value of x is 21.3
