What does X and Y equal?

Mathematics
1 answer:
Travka [436]3 years ago
4 0

Answer:

X= 67

Y= 6

Step-by-step explanation:

Triangle TRU is an equilateral triangle which means all sides are equal.

Triangles sum up to 180°.

180/3= 60

60+7= 67

x=67

Triangle TRS is an isosceles triangle which means it has two equal sides.

Triangles sum up to 180°.

180-60= 120

TRS= 120°

60/2= 30°

RTS=  30°

RST=  30°

30/5= 6

y= 6

The circumference of the base of a cone is 24 inches. The slant height of the cone is 20 inches.
loris [4]

The surface area of a cone with circumference base of 24π inches and slant height of 20 inches is 384π inches² in terms of π.

<h3>Surface area of a cone</h3>

surface area = πr(r + l)

where

  • r = radius
  • l = slant height

Therefore,

l = 20 inches

24π = 2πr

r = 12

Therefore,

surface area  = π(12)(12 + 20)

surface area = 12π(12 + 20)

surface area = 12π × 32

surface area = 384π inches²

Which list of numbers is in order from least to greatest?<br> 3/6 3/10 3/7
lapo4ka [179]
The list of numbers from least to greatest is 

3/10 , 3/7, 3/6

This is because the numerator stays the same across all three of these fractions.  However, the denominator is changing, and this proves to be a large difference.  

Think about it this way: If you cut a pie into ten pieces, then those slices are going to be smaller than if you cut the pie into seven or six pieces.

V represents video game
M represents movies
Derrick plans to spend some or all which means he can use less than that amount or the whole amount
