Answer:
131%
Step-by-step explanation:
17:13
17 ÷ 13 = 1.3076923076923 = 130.76923076923%
c. 2310 (1st pic)
circumference of circle = 2πr
44= 2 × 22/7 r
44 × 7 / (2 × 22) = r
7 = r
volume of cylinder = πr^2h
= 22/7 × (7)^2 ×15
= 2310
b. -2/x+3 (2nd pic)
(work attached)
a. 80° (3rd pic)
Total number of degrees is 180
180-(60+40)=80
c. 9 (5th pic)
(27^1/3)^2
3^2
=9
sorry i couldn't solve the 4th pic but I hope this helps!
please mark me brainliest!
Answer:
18°
Step-by-step explanation:
5x-35 = 55°
5x = 55 + 35
5x = 90
X = 18°
Answer:
(3,5)
Step-by-step explanation:
The given polygon isa pentagon and the sum of its exterior angle is 360°. The value of x from the given polygon is 8
<h3>Sum of the exterior angle of a polygon</h3>
The given polygon isa pentagon and the sum of its exterior angle is 360°.
Take the sum of the angles and equate to 360° as shown;
77 + 66 + 62+ 59 + 12x = 360°
264 + 12x = 360
12x = 96
x = 8
Hence the value of x from the given polygon is 8
