Step-by-step explanation:
I've had this equation b4
Answer:
89°
Step-by-step explanation:
Ok so the measure of a triangle is 180°.
We have one angle, so we need to find m∠ACB.
A line is 180°.
180-150= 30.
m∠ACB=30°.
m∠BAC=61°.
180-(61+30)=89°

Answer:
30 degrees
Step-by-step explanation:
A linear pair of angles add upto 180
So, y+150=180
y=180-150
=30
Answer:
8 chicken, 4 beef
Step-by-step explanation:
No. of chicken: x
No. of beef: y
x + y = 12
x = 12 - y
10x + 14y = 136
10(12 - y) + 14y = 136
120 - 10y + 14y = 136
4y = 16
y = 4
x = 12 - 4
x = 8
