X = 14
Add them all together and set them equal to 180 then solve for x
Answer:
44
Step-by-step explanation:
The equation is of the form a
x
²+bx +c = 0 where
a = 5, b= -2, c= -2
The Discriminant is given by:
Δ=
b²−
4 * a * c
= (−2²)− (
4 * 5 * (
− 2
)
)
= 4
+ 40
= 44
5/1 x 7/10 = 35/10 = 3 5/10 = 3 1/2
3 and 4
I dont know what tens-unit is, but standard form would be 60
Answer:
B = 56.25
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
cos theta = adjacent/ hypotenuse
cos B = 5/9
Take the inverse cos of each side
cos ^-1 (cos B) = cos ^-1 (5/9)
B =56.2510114
To the nearest hundredth
B = 56.25
