Answer:

The answer is the "center of rotation."

Step-by-step explanation:

The center of rotation is the point at which an image is rotated to create a second image. That is what has occurred here at point D, therefore it is the center of rotation.

Given: ΔABC; a= 10; b = 13, and ∠C = 70°. Find the length of side c to the nearest whole number

Alexxandr [17]

Answer:

$c=13\ units$

Step-by-step explanation:

we know that

Applying the law of cosines

$c^2=a^2+b^2-2(a)(b)cos(C)$

we have

$a=10\ units\\b=13\ units\\C=70\°$

substitute

$c^2=10^2+13^2-2(10)(13)cos(70\°)$

$c^2=180.07$

$c=13\ units$

4/25+1/5 in simplest form

Evgen [1.6K]

It would be 9/25. First you find the common denominator which is 25 so then you convert 1/5 to 5/25 so now you have 4/25+5/25 which you would get 9/25 and since 9 can only be divided be 3 and 25 can't your answer would be 9/25.
