Obtuse triangle

Step-by-step explanation:

For right triangle: check if 10²+12²=16²:

10²+12²=100+144=244 not equal to 16²=256.

So no 90⁰ in this triangle.

If we apply the cosine theorem:

16²=10²+12²-2×10×12×cos(A), cos(A) should be < 0 so that 10²+12²+something=16².

So the angle A >90 (its cosine<0), the triangle is obtuse.

Obs: A is the angle opposed to side of 16

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)
