Mathematics
1 answer:
Alex73 [517]3 years ago
7 0

Answer:

the answer is 2.

Step-by-step explanation:

How do I know this? well, those red arrows on the line show that those 2 sides (ED) and (AB) are congruent which means they are equal. therefore if they are equal and we know ED is 2, then we know AB is also 2. Hope this helped :)

The length of the base of an isosceles triangle is x. The length of a leg is 3x-4. The perimeter of the triangle is 97. Find x.
Ierofanga [76]

Answer:

x = 15

Step-by-step explanation:

Given that,

The length of the base of an isosceles triangle is x.

The length of a leg is 3x-4.

Perimeter, P = 97

An isosceles triangle has one base. The perimeter of a triangle is given by :

97=x+3x-4+3x-4

97 = 7x-8

97+8=7x

105 = 7x

x = 15

So, the value of x is 15.

Choose the point on the terminal side of -210°. Please only answer this question if you are willing to show work so I can learn
N76 [4]
X=rcos∅=r cos (-210)=r cos 210=rcos (180+30)=-r cos 30
x=-r* \frac{sqrt 3}{2} = \frac{- sqrt 3r}{2} ,
y=r sin (-210)=-rsin 210=-rsin (180+30)=-r(-sin 30)
1or y=r sin 30=r* \frac{ 1}{2} = \frac{r}{2}

The roads that connect three buildings form right triangle.Use the image to find the distance between the library and the museum
MAVERICK [17]
Let X = the distance you need to find.

 Using the Pythagorean Theorem we can solve for x

x = SQRT( 500^2 - 300^2)

x = SQRT (250,000 - 90,000)

x = SQRT(160,000)

x = 400

 It is 400 yards
