Answer:
Step-by-step explanation:
1. 1923.25
2.about 3846.5 yards
3.219.91
4.639.82
The exact value of cos 45 as per the special triangle would be
Cos 45 = 1/✔️2
Rationalizing the denominator gives
✔️2/2 = 0.707.
Equation :
[x(x+4)]/2=6 (as (b*h)/2=A)
x*x + 4*x -12 = 0
so, x = 2 units(as -6 is negative)
Answer:
20x - 8
Step-by-step explanation:
using the distributive property to simplify (5x-2)4, you would multiply the outside term (4) by each inside term (5x-2).
for example:
4 × 5x = 20x
4 × -2 = -8
once you distribute the 4 into 5x-2, you are left with 20x - 8 which needs no further simplifying
Sin is 5/13
We know tan = 5/12 the 5 is opposite 12 adjacent
Sin is opposite/hypotenuse. We know 5 is the opposite to find hypotenuse do pythogrean 5^2+12^2= 169 the sq rt of 169 is 13
