Answer:

41.41

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

cos theta =adjacent / hypotenuse

cos a = FD/DE

cos a = 45/60

Taking the inverse of each side

cos ^-1 ( cos a) = cos ^-1 (3/4)

a =41.40962211

Rounding to the nearest hundredth

Multiply the following and provide the product in standard from thank you
LekaFEV [45]

Answer:

x^3 + 4x^2 - 7x - 10

Step-by-step explanation:

To solve this we're going to use Polynomial multiplication, starting by multiplying (x-2)(x+1) = x^2 - 2x + x - 2 = x^2 - x - 2. Next, we will multiply (x^2 - x - 2)(x+ 5) = x^3 + 5x^2 -x^2 - 5x -2x -10 = x^3 + 4x^2 - 7x - 10.

The hypotenuse of an isosceles right triangle is 16 centimeters. Find the length of the 2 other sides of the triangle to the nea
scZoUnD [109]
Right triangle means we can use a^2+b^2=c^2
isosceles means 2 sides are equal legnths

the hypotenuse is normally the longest side so the equal sides are the other sides so therefore
a=b
therefor
(a^2)+(a^2)=c^2
2(a^2)=16^2
2(a^2)=256
divde both sides by 2
a^2=8
the side legnth of the other 2 sides is the square root of 8 which is aprox 2.8284271247452
but we only want the tenth so we look at the hundreths as well
2.82
round to the nearest tenth
2.8 cm is the answer of the legnths

It is not an "integer" because it is a "decimal value".

It is not "irrational" because the decimal value terminates and does not repeat.
