Answer:

1. 60

2. true

3.false

Step-by-step explanation:

1. All the angles in an equilateral/equiangular triangles have the same side length and the same angle, since all the angles in a triangle add up to 180 degrees, 180 divided by 3 is 60

2 and 3. An isosceles is a triangle with two equal sides. The angles opposite the equal sides are also equal. An equilateral triangle has sides of the same length.

O is the midpoint of segment FG. FO=3x+17, OG=7x-15. <br><br><br> 98 points

AlladinOne [14]

O is the midpoint so both sides FO and OG need to equal each other.

3x + 17 = 7x - 15

Subtract 3x from both sides:

17 = 4x -15

Add 15 to both sides:

32 = 4x

Divide both sides by 4:

x = 32/4

X = 8

Now you have the value of X, solve for the lengths:

FO = 3x +17 = 3(8) +17 = 24 +17 = 41

OG = 7x -15 = 7(8) -15 = 56-15 = 41

Total length would be 41 + 41 = 82

thank you for hurrying here is the very last one Explain how you would find the perimeter of this triangle.

Lena [83]

Step-by-step explanation:

Use the method of TOA CAH SOH.

$tan(51.3) = \frac{opp}{adj} \\ \tan(51.3) = \frac{u}{4} \\ u = 4 \tan(51.3)$

$cos(51.3) = \frac{adj}{hypo} \\ \cos(51.3) = \frac{4}{v} \\ v \cos(51.3) = 4 \\ v = \frac{4}{ \cos(51.3) }$

Perimeter of triangle = Sum of all sides =

$u \: + \: v + 4$

strojnjashka [21]

Step-by-step explanation:

first, add the whole numbers

6 + 7 = 13

then the fractions

3/8 + 5/6

we need to get common denominators

do you know how to do that
