C= 45
All interior angles of a triangle add to 180. 90+45=135. 180-35=45

a= 45
The top angle of the triangle and a make 90 degrees together. 90-45=45

b= 135
Angle a and b together make 180 (they are supplementary). 180-45=135

) What would the value of c be when
jasenka [17]

The value of c is 233.3

Step-by-step explanation:

Given equation is:

\frac{18}{20}c-250=-40

To find the value of c, we have to isolate c on one side of the equation

So,

Adding 250 on both sides

\frac{18}{20}c-250+250=-40+250\\\frac{18}{20}c=210

Multiplying by 20 on both sides

20*\frac{18}{20}c=210*20\\18c=4200

Dividing both sides by 18

\frac{18c}{18}=\frac{4200}{18}\\c=233.3333

Rounding off to the nearest one decimal place

c=233.3

The value of c is 233.3

Which term describes the point where the perpendicular bisectors of the three sides of a triangle intersect
MissTica

Given statement is "point where the perpendicular bisectors of the three sides of a triangle intersect".

Perpendicular is basically a vertical line that makes 90 degree angle with the base.

bisector means the line which divides side into two equal parts.

So perpendicular bisector in any triangle will be the line which is drawn on the side of the triangle and perpendicular to that side.

Now these perpendicular bisectors meet at some point.

That point is called circumcenter.


Hence final answer will be "circumcenter".

IRISSAK [1]

Answer:

Step-by-step explanation:

Assuming the decay factor, m = 0.0005

f(x) = 1 - e^{-mx}

f(9000) = 1 - e^{-0.0005*9000} =   1 - 0.0111 = 0.99
