Triangle pqr has sides measuring 9 feet and 10 feet and a perimeter of 24 feet. what is the area of triangle pqr? round to the nearest square foot. square feet

22 square foot

Step-by-step explanation:

Consider PQR be a triangle, such that PQ=9 feet, PR=10 feet.

Now, Perimeter of triangle=24

⇒Sum of all the sides=24

⇒PQ+PR+QR=24

⇒9+10+QR=24

⇒QR=5 feet

Also, s=

Area of triangle A=

=

=

=

=

≈

thus, area of triangle=22 square foot.

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)

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
