Answer:
b = 100°
c = 30°
Step-by-step explanation:
b = 100° bc the two angles are supplementary, that is, together they form a straight angle and add up to 180°.
c = 30°
because a + b + c = 180. There's 180° in a triangle.

An isosceles triangle has an angle that measures 94º. Which other angles could be in that
isosceles triangle? Choose all that apply.
43°
8°
81°
59°
Answer:
43°
Step-by-step explanation:
In a isosceles triangle, two angles HAVE to be equal.
This means that 94 can be one of the angles that are equal, or the angle that is not equal to another angle.
Let's start with the fact that 94 can be one of the angles that are equal. (Note: angles in a triangle add up to 180)
94+94+x=180
188+x=180
There is NOT a possible value for x in this situation, as you cannot have a negative value of an angle. Therefore we must try the other situation where 94 is the angle that is not equal to another angle.
x+x+94=180
2x+94=180
Subtract 94 from both sides
2x=86
Divide both sides by 2
x=43
Therefore the answer is 43°

Based on what you know about the information provided in the
graph and the roots or solutions of an equation,which function,
in factored form, does the graph below represent?*
O y = (x - 12)(x + 4)
O y = (x - 3)(x +4)
O y = (x - 12)(x-4)
O y = (x + 3)(x-4)
The function that forms the polynomial is (x + 3)(x - 4) = y
Polynomial
Polynomial is an expression that involves only the operations of addition, subtraction, multiplication of variables.
Polynomials are classified based on degree as linear, quadratic, cubic.
Quadratic polynomial is of degree two and has two roots.

96 + 150 + 2x + x = 360⁰
240 + 3x = 360⁰
3x = 120
x = 40⁰ hope it's help you
Answer: 58
Step-by-step explanation:
Since the shape has 5 sides, the sum of the internal angles is (5-2)*180 = 3*180 = 540 degrees.
Therefore, 96+150+120+2x+x = 540
386 + 4x = 540
3x = 174
x = 58

c = number of cookies baked
Adrienne baked 1200 cookies in one day
Step-by-step explanation:
Expenditure:
ingredients = $125labor/baking = $0.15 per cookieTotal = $305Part A
b) $0.15c + $125 = $305
Part B
c = number of cookies baked
Part C
0.15c + 125 = 305
⇒ 0.15c = 305 - 125
⇒ 0.15c = 180
⇒ c = 180 ÷ 0.15
⇒ c = 1200

Factor completely 4x2 16x. 4x(x 4) x(4x 4) 4(x2 4x) Prime.
Answer:
[tex]4x(x+4)[/tex]
Step-by-step explanation:
With the expression [tex]4x^{2} +16x[/tex], start by looking to see if you can take out any x-values. As you can see, both [tex]4x^{2}[/tex] and [tex]16x[/tex] have an x to the first power. You can factor that out, leaving you with the expression [tex]x(4x+16)[/tex]. Now you look for the largest numerical value that you can take out. Both 4 and 16 are divisible by 4, so you can factor out the number 4, leaving you with the expression [tex]4x(x+4)[/tex].

The area of a trapezoid is 500 square inches. The bases of the trapezoid are 16 inches and 24
inches. What is the height of the trapezoid, in inches?
Step-by-step explanation:
area = ½ (a+b) x h
500in² = ½ (16+24) x h
500in² = ½ (40) x h
500in² = 20 x h
500in²
20 = h
h = 25 inches :)
Please help me I don’t know what the answer is
Step-by-step explanation:
taking the rule of angles which state that angles on a straight line add up to 180°
then we take the solution adding the expression then equate to 180°
;5x+4+x-2+3x+7=180
like terms together
5x+x+3x+4+-2+7=180
=9x+9=180
9x=180-9
9x=171
getting the value of x we divide by nine both sides
x=171/9
x=19°
