4b-8=12
+8 +8
4b=20
Divide both sides by 4
B=5
Answer:
Step-by-step explanation:
23.m∠2=x+60
as the sides are equal.
so angles are also equal.
m∠2=45
x+60=45
x=45-60=-15°
so C
24.
74+74+m∠2=180
m∠2=180-148=32°
so 3x-4=32
3x=32+4=36
x=12°
C
25.
as the three sides are equal so angle are equal.
m∠2=60
7x-10=60
7x=60+10=70
x=10
D
Answer:
It will take it 1 and 1/2 hours.
Step-by-step explanation:
