Answer:

120.8°

Step-by-step explanation:

the total angle sum is of 360 so we add and subtract

35.8+25.4+178= 239.2

360-239.2= 120.8

so the missing angle measure is 120.8°

State the x and y-intercepts of -2x + 5y= -10

vlabodo [156]

X intercepts where y=0 , then -2x=-10, x= -10/-2, x= 5 ,
A(5,0) is x intercepts

y intercepts where x=0, then 5y= -10, y= -10/5, y= -2,
B (0, -2) is y intercepts

Make y the subject of the formula X= 4-3y/y-5

BigorU [14]

Step-by-step explanation:

X= 4-3y/y-5

x(y-5) = 4-3y

xy -5x = 4 -3y

xy+3y = 4+5x

y(x+3)= 4+5x

y = (4+5x)/(x+3)

Let d = # digital cameras
Let m = # manual cameras

d + m = 240 equation 1

(d-82) = 3(m-26) equation 2
d - 82 = 3m - 78
d - 3m = 82 - 78
d - 3m = 16 equation 2 simplified

We have two equations with 2 unknowns:

d + m = 240
d - 3m = 16 subtract equation 1 from equation 2
---------------
-4m = -224
m = -224/-4
m = 56

d + m = 240
d = 240-m
d = 240-56
d = 184

He started with 184 digital cameras and 56 manual cameras
