Find the ratio of two complement angle is 2:3. Find the angles.​

Mathematics
1 answer:
Aliun [14]3 years ago
8 0

Answer:

The angles are 2x= 2x18°   =36° and  3x=3×18   =54°  

Step-by-step explanation:

It is given that two complementary angles are in the ratio 2:3.

Consider 2x and 3x as the angles.

We know that, if two angles are complementary, then their sum is 90°    .

Then, 2x+3x=90°  

 ⟹ 5x=90°  

⟹ x=  90/5

​  x=18°  

Here, the angles will be 2x=2×18   °=36°  

 and 3x=3×18°   =54  °

Hope this helps.

A tank in the shape of a right rectangular prism measures 10 inches long, 5 inches wide, and 7 inches tall. The tank is filled w
fgiga [73]

Answer:

Approximately 149 cubic centimeters of water

Step-by-step explanation:

step 1

Find the volume of water in the tank

The volume of a rectangular prism is equal to

V=LWH

we have

L=10\ in\\W=5\ in\\H=7\ in

substitute

V=(10)(5)(7)=350\ cm^3

step 2

Find the volume of the cylindrical container

The volume of the cylinder is equal to

V=\pi r^{2}h

we have

r=4/2=2\ in ---> the radius is half the diameter

h=1.6\ in

\pi =3.14

substitute

V=(3.14)(2)^{2}(1.6)

V=20.096\ cm^3

step 3

To find out how much water is still in the tank, subtract the volume of 10 containers of water from the volume of the tank

so

350-(10)(20.096)=149.04\ cm^3

therefore

Approximately 149 cubic centimeters of water

The complete question in the attached figure N 1

see the attached figure N 2 to better understand the problem

we know that

sin 26°=y/14-------> y=14*sin 26°------> y=6.14 ft

the answer is
<span>The height of the ramp is about 6.14 ft</span>
