Find the missing angle:

40

Step-by-step explanation:

Use this picture as a reference.

So, using remote angles theorem, which states that; the angle formed from the extension of a side in a triangle is equal to the sum of the two angles which it does not make contact with, within the triangle. One can conclude that :

m< BCD = m<B + m<A

substitute:

m<BCD = 80 + 25

Simplify:

m<BCD = 105

Since it is given that m< BCE is 50, then  one has to subtract m<BCE from m<BCD to get m<ECD

m<BCD - m<BCE = m<ECD

Subsitute:

105 - 50 = m<ECD

Simplify:

55 = m<ECD

Using the sum of angles in a triangle, which states that the sum of all the angles in a triangle is 180 degrees, one can say that:

m<D + m<ECD + m<E = 180

Substitute:

85 + 55 + m<E = 180

Simplify, inverse operations:

140 + m<E = 180

-40               -140

m<E = 40

step-by-step explanation:

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
