Use the law of cosines to solve for the measure of the largest angle in triangle abc.

The measure of the largest angle in ΔABC = 98°

Step-by-step explanation:

The longest side in the given ΔABC is AB

And, The angle opposite to the longest side is largest

⇒ ∠C is the largest angle. in the ΔABC

So, we need to find the measure of ∠C

Now, Using law of cosine in the given ΔABC :

⇒ 16² = 9² + 12² - 2 × 9 × 12·cos C

⇒ 216·cos C = 81 + 144 - 256

⇒ 216·cos C = -31

⇒ cos C = -0.14352

⇒ m∠C ≈ 98°

Hence, The measure of the largest angle in ΔABC = 98°

stew reads at the fastest rate of 265 words per minute.

step-by-step explanation:

it's a given that felicia reads at 260 word per minute and on connie's graph we can see that she reads 200 words per minute. since stew's table tells us that he read 795 in 3 minutes, we can divide 795 by 3 to find out how many words he reads per minute.

795/3 = 265

stew reads 265 words per minute - he reads at the fastest rate since felecia reads at 260 words per minute and connie reads at 200 words per minute.

stew (265) > felecia (260) > connie (200)

just take the area of the square and then the area of the circle then subtract the circle area from the squares area
