Step-by-step explanation:
a+b+c=180°
64°+b+c=180°
b=c
2b+64°=180°
2b=180-64
2b=116°
b=116/2
b=58°=c
Answer:
x=55°
Step-by-step explanation:
x=90-35
x=55°
(because its x+35=90°)
Step-by-step explanation:
Root:(1/2, 0)
Domain: x∈R
Range: y∈R
Vertical intercept: (0, 1)
The top question is B. 30, because you have to set 7y-30 equal to 4y+60 since both lengths are the same.
