17. given the side measures, which of the following could form a right triangle?
a. 61m, 60m, lim
b. 24in, 34in, 28in
c. 55ft, 45ft, 35ft
d. 48cm, 46cm, 15cm

Choice A forms a right triangle.

Step-by-step explanation:

I am assuming  the last side in choice A is 11 m.

61^2 = 3721

60^2 + 11^2 = 3721

This satisfies  the Pythagoras theorem so this is a right-angled triangle.

The others are not right angled.

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
