Answer:

D

Step-by-step explanation:

The Angle Sum Property of a Triangle states that the internal angles of a triangle add up to 180°
Here, the sum is : 130 + 30 + 30 = 190°
Therefore, the angle measurements are not correct
The total angle measure of triangle should decrease by 10°
By making the top angle 120°, the sum becomes 180°
Hence, D is the correct option

Rs = 8y + 4 , ST = 4y + 8 , and RT = 36 , find the value of y

Natasha_Volkova [10]

I assume that you meant RS and ST are segments of RT. If that is true then:

RS+ST=RT, using the values for these given...

8y+4+4y+8=36 combine like terms on left side

12y+12=36 subtract 12 from both sides

12y=24 divide both sides by 12

y=2
