Answer:

D. 100°

Step-by-step explanation:

A straight line is 180°. Add 50° and 30° (which is 80°) and subtract the total from 180°.

50 + 30 = 80

180 - 80 = 100

Answer:

These angles form a straight line, so they are supplementary angles.

We know that, supplementary angles form 180°.

50 + x + 30 = 180 \\ 50 + 30 + x = 180 \\ 80 + x = 180 \\ x = 180 - 80 \\ x = 100

=> So, the missing angles is <u>100°</u>

What is the degree of the monomial 2b^8c^2?
navik [9.2K]
A monomial is a polynomial with a single mathematical term. To clarify a polynomial would be 4x^3 + 3x^2 + 3 where as a monomial would be a single term such as 4x^3. The degree of a monomial is the sum of all exponents in the term. In this case the degree is 1+8+2=11. This is because the 2 also has the intrinsic exponent of 1.

A rectangular dog pen is constructed using a barn wall as one side and 60 meters of fencing for the other three sides. What is t
Sever21 [200]

Answer:

450 m^2

Step-by-step explanation:

let the length be y m (the single side)

let the width be x m

so according to the question

2x + y = 60

or, y = 60 - 2x

now, Area = xy

= x(60-2x)

= -2x^2 + 60x

d(Area)/dx = -4x + 60

= 0 for a max of area

-4x + 60 = 0

x = 15

then y = 30

the width has to be 15 m, and the length has to be 30 m for a maximum area of 15(30) or 450 m^2.

What is the value of x? Please explain the step process to getting to the conclusion.
olga55 [171]

First, split the triangle into half.

So the angle 38 becomes 38/2=19.

So we know two angles in the triangle:

One is 19 degrees.

The other one is 90 degrees (marked red).

The angles in a right-angled triangle add up to 180 degrees.

So to find the x angle, we calculate it by:

180 - (90+19) = 71

(the sum of three angles) - (the sum of the two known angles) = unknown angle

So x = 71 degrees.
