Answer:
Step-by-step explanation:
The figure is composed of two similar triangles; therefore,
<em>this says the ratio of the sides is same for the two triangles.</em>
we simplify and a rearrange to get
which we expand and get
this quadratic equation has solutions
As integers and simplified fractions these are
Answer:
answer C is the right one
Step-by-step explanation:
Volume cylinder is area of the (round) surface * height.
The formula for the area of any circle = pi * radius²
pi * radius²
So the formula for the volume is
Volume cylinder = pi * radius² * height
radius = 15 in and height = 6 in
Substitute this in the formula and you get:
Volume cylinder = pi * 15² * 6
Volume cylinder = pi * 225 * 6
Volume cylinder = pi * 1350
so answer C is the right one
Step-by-step explanation:
it's an Equilateral triangle
the base angels are equal
A=100°
B=40°
C=40°
Answer:
135°
Step-by-step explanation:
To convert from radians to degrees
degree = radian × 
Thus for 
degree = × ( cancel the π )
= 
= 
= 135°
