x+60 =180

x = 120.

y+x =18

35+25=60
y=60

If you add the opposite side values of the triangle (not the one touching the y), you get the value of y). 35+25=y
This works because y+x= 180 and the three angles of a triangle add to 180.

Answer:

I'll setup the problem and you can do the calculations

Step-by-step explanation:

$V = \pi( {D}^{2} \div 4)H$

V = volume; D = diameter; H = height of can

Area of the Tin is the total area of the 2 Tin circles

one circle's area A is

$A = \pi {D}^{2} \div 4$

A = area; D = diameter

calculate A

Then multiply by 2

The area of the cardboard is the circumstance of the circle

times the height

$SA = \pi DH$

Find all missing angles <br> y+30+2y=180

kirill [66]

Answer:

Step-by-step explanation:

y+30+2y=180

Add like terms

3y+30=180

Subtract 30 on both sides

3y=150

Divide by 3 on both sides

y=50

Now all you have to do i calculate the angles.

Just apply the Pythagoras Theorem,

LN² = LM² + MN²

LN² = 7² + 8²

LN² = 49 + 64

LN = √113

In short, Your Answer would be: Option D

Line L passes through the points (0 - 3) and (6,9).

Luden [163]

a) find the slope of the line using the given points.

Slope: 9 - -3/6-0 then slope is 12/6 which is 2

Then using formula: y = mx+b

-3 = 2(0) + b

b = -3

The equation is: y = 2x -3

B. Slope of a perpendicular is -reciprocal of first line. So here the slope will be -1/2
