Serggg [28]3 years ago
6 0

Step-by-step explanation:

h(x)=-4x-10

but h(x) =-30

-30=-4x-10

-4x=-10+30

-4x=40

-4x/4=40/4

x=10

What is the measure of an angle if it is 260 degrees less than six times its own complement?
poizon [28]

Answer:

40 degrees

Step-by-step explanation:

Complementary angles have a sum of 90.

y = 90 - x

The angle is 260 degrees less than six times its complement.

y = 6x - 260

90 - x = 6x - 260

350 - x = 6x

350 = 7x

50 = x

This is the measure of the complement.

y = 90 - x

y = 90 - 50

y = 40

This is the measure of the first angle.

HELP any1 good at math?
valentina_108 [34]

Step-by-step explanation:

the equations are :-

=》d = 40m + 200

=》d = 50m

here, by equalising both equations.

( since, d = d )

=》40m + 200 = 50m

=》50m - 40m = 200

=》10m = 200

=》m = 200 ÷ 10

=》m = 20

now,

=》d = 50m

=》d = 50 × 20

=》d = 1000

A circle has a sector with area 45/4 pi and central angle of 9/10 pi radians. What is the area of the circle?
Nikitich [7]

Answer:

the area of the circle: 25π

Step-by-step explanation:

45/4 π = 11.25π

9/10π = 0.9π

11.25π / 0.9π = x / 2π   .... 360° = 2π

x = (11.25π x 2π) / 0.9π = 25π

= (x - 3)^2 - 1


the vertex is at (3,-1)
