Polygon ABCDEF has 6 sides. A is 170° C is 133° D is 102° he is 117° and F is 90°. What is the measure of b?

Zielflug [23.3K]

Answer:

$B = 134^o$

Step-by-step explanation:

$n = 6$ --- sides

$A = 170^o$

$C = 107^o$

$D = 102^o$

$E = 117^o$

$F = 90^o$

Required

The measure of B

The interior angles of a polygon is:

$Angles = (n - 2) * 180$

So, we have:

$Angles = (6 - 2) * 180$

$Angles = 4 * 180$

$Angles = 720^o$

The measure of B is calculated using:

$A + B + C + D + E + F = 720$

Substitute known values

$107 + B + 170 + 102 + 117 + 90 = 720$

Collect like terms

$B + 107 + 170 + 102 + 117 + 90 = 720$

$B + 586 = 720$

Collect like terms

$B = 720 - 586$

$B = 134^o$

If you can answer this you are a star , plzz i need help

BlackZzzverrR [31]

Answer:

$\left[\begin{array}{ccc}9\\10\\\end{array}\right]$

Step-by-step explanation:

Multiply the components of A by 3 then add corresponding components of

3a + b

3 $\left[\begin{array}{ccc}2\\4\\\end{array}\right]$ + $\left[\begin{array}{ccc}3\\-2\\\end{array}\right]$

= $\left[\begin{array}{ccc}6\\12\\\end{array}\right]$ + $\left[\begin{array}{ccc}3\\-2\\\end{array}\right]$

= $\left[\begin{array}{ccc}6+3\\12-2\\\end{array}\right]$

= $\left[\begin{array}{ccc}9\\10\\\end{array}\right]$

Convert the density of surface sea water to metric tons/cubic meter.

ryzh [129]

Answer: 1.029 tons/m³

Step-by-step explanation:

Density of sea water may varies for different temperature but at 25°C the density of sea water is taken as 1029 kg/m³.

Density of sea water is 1029 kg/m³

1 tons=1000 kg

1 kg=0.001 tons

Density of sea water=1029×0.001 tons/m³

=1.029 tons/m³

hence the density will be 1.029 tons/m³
