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

b. 29, 52.2, 52.2 or 29, 29 69
8. a. 402 - 237(x/15)
b. 11
c. 12

A tree is 7 ft tall when it is planted and this type of tree grows two feet per year. How tall will the tree be in 6 years? How
s344n2d4d5 [400]

2x+7=?

X=6

2(6)+7=

12+7=19

In six years, the tree will be 19ft

2x+7=44

Minus seven on both sides

2x=37

Divide two from both sides

X=18.5

Thus, it will take 18 and a half years for the tree to reach 44ft

Translate the following word phrase into an algebraic expression: nine times five less than twice x.
bagirrra123 [75]

The given statement is "nine times five less than twice x".

So, twice of x can be written as 2x and nine times five is 9*5.

Now 9*5 less 2x means we need to take out 9*5 from 2x.

Hence, this statement will be converted into an algebraic expression as follows:

2x-9*5

The gcd of two numbers is 7 and their lcm is 140. If one of the numbers is 20 find the other number ​
sweet [91]

Answer:

49

Step-by-step explanation:

Product of GCD and LCM = Product of the 2 numbers

Product of GCD and LCM = 7 × 140 = 980

One number is 20 so let the other number be N

20×N=7×140

20N=980

2N=98

N=49

so the other number is 49
