Answer: 17

Step-by-step explanation:

<h3> \frac{4+4^{2} }{2} +∣13−20∣</h3>

Calculate 4 to the power of 2 and get 16.

<h3>\frac{4+16 }{2} +∣13−20∣</h3>

Add 4 and 16 to get 20.

\frac{20}{2}∣13−20∣

Divide 20 by 2 to get 10.

10∣13−20∣

Subtract 20 from 13 to get -7.

10∣-7∣

The absolute value of a real number a is a when a≥0, or −a when a<0. The absolute value of −7 is 7.

She's rounding down. Thinking you use the number from the hundred place. You round using the tens place. It's over 50 so u go off the 75 in this case ending up with 1,300

the hypotenuse of a 45°-45°-90° triangle measures 128 cm. What is the length of one leg of the triangle? 64 cm cm 128 cm cm
Kisachek [45]

Answer:

length of one leg of the triangle is 64 cm.

Step-by-step explanation:

Given : The hypotenuse of a 45°-45°-90° triangle measures 128 cm.

To find  : What is the length of one leg of the triangle.

Solution : We have given that hypotenuse of a 45°-45°-90° triangle measures 128 cm.

By the 45°-45°-90° triangle rule ,

Perpendicular sides  (legs) are equal .

Hypotenuse  =  √2 × either perpendicular side ( leg ).

128 = √2 ×  leg .

We can write 128 as  64 √2 and substitute in above

64√2 = √2 leg.

On dividing by √2 both sides and switching sides.

leg  = 64 cm .

Therefore,  length of one leg of the triangle is 64 cm.
