The pie chart shows information about the voters in an election 2800 more women voted than men work out the total number of vote

Cerrena [4.2K]

The angle subtended by the women voters are 100° more than the angle subtended by the men voters.

The total number of voters are <u>10080 voters</u>

Reasons:

The angle subtended by the men on the pie chart = 130°

The number of women = 2800 + The number of men

Therefore;

Angle subtended by the women voters on the pie chart = 360° - 130° = 230°

The difference between the angle representing women and the angle

representing men = 230° - 130° = 100°

Therefore;

100° = 2800

Which by common ratios gives;

$\dfrac{100^{\circ}}{360^{\circ}} = \dfrac{2800}{Total \ number \ of \ voters }$

100 × Total number of voters = 2800 × 360

$The \ total \ number \ of \ voters = \dfrac{2800 \times 360}{100} = 10080$

The total number of voters = <u>10080</u>

Cloud [144]

Y + 4 = 2(x - 1)
y + 4 = 2x - 2
-2x + y = -2 - 4 = -6

If sin theta = cos theta then find the value of theta

Ksenya-84 [330]

Step-by-step explanation:

$\because \sin \theta = \cos \theta \\ \\ \therefore \: \sin \theta = \sin(90 \degree - \theta) \\ \\ \therefore \: \theta = 90 \degree - \theta \\ \\ \therefore \: \theta + \theta= 90 \degree \\ \\ \therefore \: 2\theta = 90 \degree \\ \\\therefore \: \theta = \frac{90 \degree }{2} \\ \\ \huge \orange{\boxed{\therefore \: \theta = 45 \degree}}\\ \\$
