The measure of AngleRST can be represented by the expression (6x + 12)°. Three lines extend from point S. The space between line
s S R and S U is 78 degrees. The space between lines S U and S T is 3 x minus 12. What is mAngleRST in degrees?
1 answer:
Answer:The measure of angle RST is 120\°
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
m<RST=(6x+12)\° -----> equation A
m<RST=78\°+(3x-12)\° -----> equation B
equate equation A and equation B
(6x+12)\°=78\°+(3x-12)\°

No. Mina put the whole number 10 over one of the fractions when she should have put it over 1
Should be c ? can you send me a picture please ? and it’s dice .
Answer:
y-intercept=-5
Step-by-step explanation:
y=mx+b m/slope=3/2 the point is (x,y)/(4,1)
1=3/2(4)+b
1=12/2+b
1=6+b
-6-6
-5=b
