Find y of this triangle.

Mathematics
1 answer:
kvasek [131]3 years ago
8 0

Answer:

y =52

Step-by-step explanation:

We know that the angles 4x and 5x make a straight line

4x+5x = 180

9x = 180

Divide by 9

9x/9 = 180/9

x = 20

The three angles of a triangle make 180

y + 48 +4x = 180

y + 48+4(20) =180

y + 48 +80 = 180

Combine like terms

y +128 = 180

Subtract 128 from each side

y + 128-128 = 180-128

y =52

Elena L [17]

Answer:

210 m

Step-by-step explanation:

Perimeter is the distance around the outside of a two-dimensional shape.

Area is the space inside of a two-dimensional shape. We can also think of area as the amount of space a shape covers.

Christen ran around the soccer field, so she ran around the perimeter.

We can find the perimeter by adding all of the side lengths.

Perimeter=60 m+45 m+60 m+45 m

Christen ran 210m.

Sarah has a wall hanging in the shape of a parallelogram. What is the height of the wall hanging if its area and base are 300 sq
Anastasy [175]
Use the formula
Area= base times height.
You're given that area =300cm^2 and base=20 cm.
Plug these into the equation to get 300=20 x height. Now, you just need to solve for height. To do this, you need to undo the multiplication of b x h by dividing the area by the base.
So, h = 300/20

Fatima plotted one side of a heptagon on a grid. the points (-8,1) and (-8,8) are joined to form a side of the heptagon. Fatima
Reil [10]

The general formula for the distance between two points is

d(A,B) = \sqrt{(A_x-B_x)^2 + (A_y-B_y)^2}

Anyway, if A and B have the same x or y coordinates, this formula can be simplified. For example, in this case the two points have the same x coordinate of -8, so the following part of the formula simplifies:

(A_x-B_x)^2 = (-8-(-8))^2 = (-8+8)^2 = 0^2 = 0

So, we're left with

d(A,B) = \sqrt{(A_y-B_y)^2}

but the square root of a square is the absolute value of the object being squared:

d(A,B) = \sqrt{(A_y-B_y)^2} = |A_y-B_y|

which is this case means |1-8| = |-7| = 7

which is the correct length of the side.
