A. Line that equals 7 must be perpendicular due to the triangle being isosceles. Use Pythagorean theorem on one of the triangles to find that the missing length is 5. 5 can be multiplied by 2 because the triangles are congruent. So x=10.

frosja888 [35]

Hello!

Let's put this as a system of equations.

r= 8+g

r+g=14

Let's plug our r value into the second equation and solve for g.

8+g+g=14

8+2g=14

Now we subtract 8 from both sides.

2g=6

We divide both sides by 2.

g=3

Therefore, he has 3 green peppers.

I hope this helps!

Find the value of x :)
alexira [117]

Answer:

x = 20

Step-by-step explanation:

→ Remember how many degrees are on a straight line

180°

→ Set up an equation

2x + 70 + 3x + 10 = 180

→ Simplify

5x + 80 = 180

→ Minus 80 from both sides

5x = 100

→ Divide both sides by 5

x = 20

mojhsa [17]
<h2>QUESTION:- What is the value of y?</h2>

<h2>ANSWER:- </h2>

SUM OF ALL INTERIOR ANGLE = 180

y + y + 72 = 180 \\ 2y + 72 = 180 \\ 2y = 180 - 72 \\ 2y = 108 \\ y =  \frac{108}{2}  \\ y =  \frac{ \cancel{108}^{ \:  \:  \:  \tiny{54}}  }{ \cancel{2}}  \\ y = 54 \degree
