Which best describes the triangle or the triangles, if any, that can be formed with two sides that measure 5 inches and an angle that measures 60 degrees? two different isosceles triangles no triangle one isosceles triangle one equilateral triangle

Answer with explanation:

Suppose the two sides of triangle are, 5 inches and angle between the two sides is 60 degrees.

We will use cosine formula to find third side.Let side opposite to angle having measure 60 degree, is equal to a inches.

Omitting, a= -5, because side can't be negative.

So, third side = 5 cm.

Means, triangle is equilateral.

If angle between , two sides having measure 5 cm , is not 60 degree, then the triangle will be always Isosceles.

we will sine rule to find remaining measurements.

In this case,also ,triangle is equilateral.

Option D: one equilateral triangle

the answer is 4.8 units on e2020.

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!
