Because ABC and DEF are congruent.

m∠A = m∠D

m∠B = m∠E

m∠C = m∠F.

We need m∠B = m∠E.

m∠B = 65⁰

m∠E = (x-8)⁰

65 = x-8

x=65 + 8 = 73⁰

Answer: x=73⁰.

Δ ABC ≡ ΔDEF

⇒ ∠DEF = ∠ABC

<u>Solve x:</u>

x - 8 = 65

x = 73

Answer: x = 73°

Answer: Domain: x=-2. Range: -2<=y<1

Step-by-step explanation:

Domain: The line is only on one x-point and that is x=-2.

Range: The line is ranging form -2 to 1. However, y=1 is not included on the line but y=-2 is. Hence, the range is notated as -2<=y<1.

A telephone company charges its customers per minute to make long-distance calls. The cost, c, can be represented by c = .12m wh

Ksivusya [100]

Answer:

m ≥ 0

Step-by-step explanation:

Since the cost is represented by c = 0.12m, the domain should be a positive number, this is because number of minutes can't be written in negative. Therefore, the most reasonable number for the domain would be the set of positive whole numbers which means, m≥0.

The length of the base of an isosceles triangle is x. The length of a leg is 4x-6. The perimeter of the triangle is 60. Find x.

lbvjy [14]

Answer:

Perimeter of a triangle = add all sides

Both the legs of the isosceles triangle are always EQUAL.

x+4x-6+4x-6 = 60

9x-12 = 60

9x = 60+12

9x = 72

x = 8
