Rainbow [258]

Answer:

144°

Step-by-step explanation:

We are asked to convert 4π/5 radians to degrees.

#We know that:

$1 \ rad= 57.296\textdegree =180/\pi$

Therefore, we multiply 4π/5 radians by 180/π to get its degrees equivalent:

$=\frac{4\pi}{5}\ rad\times \frac{180}{\pi}\\\\=144\textdegree$

Hence, the degrees equivalent of 4π/5 rad is 144°.

Figure A is enlarged to create figure B. The ratio of the areas of A and B is 16:49.

Nadusha1986 [10]

Answer: $\dfrac{20}{7}$

Step-by-step explanation:

Given

The ratio of the area of the similar triangles is equal to the square of the side of the corresponding sides

Suppose the corresponding side on figure A is $x$

On solving

$\Rightarrow \dfrac{16}{49}=[\dfrac{x}{5}]^2\\\\\Rightarrow \dfrac{x}{5}=\sqrt{\dfrac{16}{49}}\\\\\Rightarrow \dfrac{x}{5}=\dfrac{4}{7}\\\\\Rightarrow x=\dfrac{20}{7}$

No entiendo ayudaaaa

hram777 [196]

This is a pythagorean theorem problem therefore a^2+b^2=c^2
a=8, b=?, c=10
8^2+b^2=10^2
64+b^2=100
100-64=56
square root of b^2=square root of 56
b=2 rad14
2 rad14 +4=
2 (rad14 + 1)= ANSWER
