Answer: x= 25
Angles = 45, 60, 75
Step-by-step explanation:
(X+20) +3x+60 = 180
(X+20)+3x= 180-60= 120
X+20+3x= 120
X= 25
25 + 20=45
25*3= 75
Answer:
Step-by-step explanation:
<u>Use the formula for angle formed by the chords:</u>
- Angle formed by 2 chords = 1/2( sum of intercepted arcs)
<u>Let the supplementary angle of x be y</u>
- x + y = 180 (straight angle)
<u>Find the value of y, using the above mentioned formula</u>
- y = 1/2(168 + 40) = 1/2(208) = 104
<u>Find the value of x:</u>
- x = 180 - y
- x = 180 - 104 = 76
Correct choice is C
I believe the sphere doesn't belong with the other three. It has no edges or corners/vertices.
Answer:
Step-by-step explanation:
Since argument is the value of independent variable x .
Here y= 1 when x = 0.
Taking integration on both sides , we get
Put y=1 and x=0 [given] , then
Hence, the function will be
