<h2>option b. 52, 48 and 20</h2>
Step-by-step explanation:
<u>let's solve:-</u>
- To test whether given this triangle is right triangle or not, we can use the Pythagorean Theorem .
soo
Pythagorean Theorem=

The distributive property: a(b + c) = ab + ac
12(6k + 3) + 4(7 - 5k) = 12(6k) + 12(3) + 4(7) + 4(-5k)
= 72k + 36 + 28 - 20k = 52k + 64
If<span> the degree </span>measure<span> of </span>two<span> complementary </span>angles<span> are in the ratio of </span>1<span>:14, ...
