2x+2x+6x= 180
10x=180
X= 18
Angle C = 36
Your answer is 98
This is because. u (18) + xy (10 × 8 = 80) so
18 + 80 = 98
Hope this helped
Answer:
39.30 
Step-by-step explanation:
The area of the top surface of the wedge is the same as the area of a sector.
Area of a sector = (θ/
)

where: θ is the central angle, and r is the radius.
Given that: central angle =
, radius = 10 centimetre.
Area of the top surface = Area of a sector = (θ/
)

=
x
x 
=
x
x 100
= 39.2857
= 39.30 
The area of the top surface of the wedge is 39.30
.
Answer:
37.7
Step-by-step explanation:
<h2><u>circumference of a circle:</u></h2>
Formula = 2πr
r is the radius
diameter = 2* radius
hence radius = 12/2
radius = 6 yards
2*π*6 = 37.6991
to 3sf
<h3><u>circle circumference is 37.7</u></h3>
