PLEASE HELP ME 40 POINTS

Mathematics
1 answer:
n200080 [17]3 years ago
4 0

Answer:

y=27

Step-by-step explanation:

Fact 1: The sum of two adjacent angles formed by the intersection of two lines is 180.

So, x+146=180

=>x=34

Fact 2: The sum of the inscribed angles in a triangle is 180.

So, (5y+3)+(4y+8)+34=180

=>5y=180-45

=>5y=135

=>y=27

Answer both question for 20 points and brainliest
Dmitrij [34]

Answer:

1 - c

2 - A

Step-by-step explanation:

Hey There!

So for the first one we are given the dimensions of a rectangular prism and they want us to find the volume

Remember to find the volume we use the equation

V = length x width x height

so we just plug in the values

v = 2.6 x 2.1 x 3.9 = 21.294

the closest is 20 so C is your answer

For the second one we are given a triangular prism

and they want us to find the volume

V=\frac{1}{2} bhl

b = base (10.3)

l = length (4)

h = height (7)

7x4=28

28x10.3=288.4

then we divide by 2

288.4/2=144.2

so your selected answer is correct
