Answer:

Step-by-step explanation:

The area of a triangle is 1/2 bh

b= base, in this case 12 cm

h= height, in this case 5 cm

so you multiply 5 times 12 and you get 60

You take that 60 and half it to get your answer of 30.

Given the line y =2/3x-3

enyata [817]

Answer:

y= -3/2x + 5

Step-by-step explanation:

You do the opposite reciprocal of the original equation's slope.

Then you use the new slope from the point (4,-1) on the graph to find the y-intercept. Which is (0,5).

That gets your answer of -3/2x + 5.

Geometry Question: BK bisects angle ABC and M angle ABK=28.3 degrees. Find M angle KBC and M angle ABC.

GarryVolchara [31]

Answer:

$KBC = 28.3$

$ABC = 56.6$

Step-by-step explanation:

Given

$ABK = 28.3$

Required

Determine KBC and ABC

Since BK bisects ABK, then

$KBC = ABK$

Substitute 28.3 for ABK

$KBC = 28.3$

Using same point as above

<em>Since BK bisects ABK, then</em>

$ABC = ABK + KBC$

$ABC = 28.3 + 28.3$

$ABC = 56.6$
