since this is an isosceles triangle

5x =40

divide by 5

x=8

the sum of all angles in a triangle is 180

5x+40 + 2y+20 = 180

substitute 40 in for 5x

40 + 40 + 2y+20 = 180

combine like terms

100 + 2y = 180

subtract 100 from each side

2y = 80

divide by 2

y= 40

Y=40 because x=8 making the two bottom angles 40 each and leaving the last angle to be 100 and 100+40+40= 180. Hope this help

As a 42.4 foot long pipe comes off the manufacturing line it is cut into 0.80 foot long sections. How many smaller sections are
Ludmilka [50]

53 smaller sections are created from the larger pipe

Step-by-step explanation:

The number of smaller section will be obtained by dividing the length of long pipe by the length of small section.

Given

Length of long pipe= 42.4 feet

Length of small section = 0.80 foot

Total\ number\ of\ sections=\frac{Length\ of\ large\ pipe}{length\ of\ one\ small\ section}\\=\frac{42.4}{0.80}\\=53

53 smaller sections are created from the larger pipe

If the average (arithmetic mean) of 3a and 4b is less than 50, and a is twice b, what is the largest integer value of a?
sdas [7]

Answer: The largest value of 'a' is less than 20

Step-by-step explanation:

If arithmetic mean of 3a and 4b is less than 50 i.e 3a+4b/2 < 50

3a+4b < 100... (1)

If a is twice as b, a = 2b... (2)

Substituting equation 2 into 1 we have, 3(2b)+4b < 100

6b+4b < 100

10b < 100

b < 10

Since a = 2b, a = 2×10 = 20

Therefore the largest value of 'a' is less than 20 which can be 19.9
