Let's call our unknown angle x .
We know that the sum of the three interior angles of a triangle is 180°
This way,

We get that the third angle measures 29°

Answer:
She will have 12 sections per fabric and 36 sections in all
Step-by-step explanation:
Betty buy 3 fabrics of 30 ft²
If she cut each to 2/5 of 1 ft²
The she will have
30 × 2/5
= 6 × 2
= 12
She will have 12 for each fabric and for the 3 fabrics, she will have
12 × 3 = 36
Answer:
Step-by-step explanation:
One rider's rate is x....the other is x+4
Once they pass each other, they travel for 1.5 hrs...and the combined distance they travel = 39 km
So....Rate x Time = Distance....and we have
x(1.5) + (x+4)(1.5) = 39 simplify
1.5x + 1.5x + 6 = 39
3x + 6 = 39 subtract 6 from both sides
3x = 33 divide by 3 on both sides
x = 11 km/hr this si the slower rider's rate
x + 4 = 11 + 4 = 15 km/hr and this is the faster rider's rate
I think it may be this but you need to round=
