9) If m/1 = 45° and 21 and 22 are complementary angles. Find m22.​
Allisa [31]

❄ Hi there,

keeping in mind that the sum of complementary angles is 90°,

set up an equation, letting \angle2  be x  –

\triangleright \ \sf{\angle1+x=90}                 {and we know that \boxed{\angle1=45}}

\triangleright \ \sf{45+x=90}

\triangleright \ \sf{x=90-45}

\triangleright \ \sf{x=45}

\triangleright \ \sf{\angle2=45\textdegree}

      __________

Keeping in mind that a right angle is 90°,

set up an equation, letting \angle1 be x:

\triangleright \ \sf{x+\angle2=90}                       {and we know that \boxed{\angle2=63}}

\triangleright \ \sf{x+63=90}

\triangleright \ \sf{x=27}

\triangleright \ \sf{\angle1=47\textdegree}

B) The number of volume of a cylinder is half of its number of the total surface area.
faust18 [17]

Answer:

V=179.6cm^3

Step-by-step explanation:

the volume of a cylinder is given by:

V=\pi r^2h

where r is the radius and h is the height.

and the surface area:

SA=2\pi r^2+2\pi rh

the first term is the area of the circles and the second term is the area of the body.

since "The number of volume of a cylinder is half of its number of the total surface area." we will have that:

V=\frac{1}{2}SA

substitutig the equivalent expressions on each side:

\pi r^2 h = \frac{1}{2} (2\pi r^2+2\pi r h)

and we simplify and solve for the height (since is the value we don't know of the cylinder):

\pi r^2 h = \pi r^2+\pi r h\\\pi r^2h-\pi rh=\pi r^2\\h(\pi r^2-\pi r)=\pi r^2\\h=\pi r^2/(\pi r^2-\pi r)

we substitute the value of the radius r=7cm, and we get:

h=\pi (7cm)^2/(\pi (7cm)^2-\pi (7cm))\\h=153.938/(153.938-21.991)\\h=153.938/131.947\\h=1.1666cm

thus the volume is:

V=\pi r^2h

V=\pi (7cm)^2(1.1666cm)\\V=179.6cm^3
