The area of the associated sector is: 120π

<h3>What is a sector?</h3>

A sector is the portion of the area of a circle surrounded by an arc and two radii.

∅ = 75°

r = 24 units

Area of sector = 75/360 x π(24)^{2} = 120\pi square units

What would z and x equal i need help plz
KATRIN_1 [288]

Answer:

Angle Z =79°        and x = 31.33

Step-by-step explanation:

From the shown parallel and intersecting lines , it is found that,

∠z° = 79°      interior angle on same side of transversal

and ∠z = (6x - 109°)                   corresponding angles

i.e 79°+109°=  6x

or, 188 = 6x

i,e x = 31.33

Hence angle z =79°   , and x  = 31.33

What is the value of y in the equation 5x + 2y = 20, when x = 0.3?
vlada-n [284]
Y=9.25 because inorder to solve this we need to first take 5*.3 which equals 1.5 now that we have this we can move on we now have the equation 1.5 + 2y = 20 so now we need to continue working on getting y by it self so we subtract 1.5 from each side and then that leaves us with 2y=18.5 now we divide by 2 which leaves us with y=9.25
