Answer:
x=
x=-
Step-by-step explanation:
For this case we have the following equation:
sine (40) = b / 20
From here, we must clear the value of b.
Clearing we have:
b = 20 * sine (40)
b = 12.85575219
Rounding to the nearest tenth we have:
b = 12.86 cm
Answer:
b = 12.86 cm
Answer:
Do you want it in algebra terms or in geometry terms?
Step-by-step explanation:
Answer:x=13
BMC=75 degrees
Step-by-step explanation:
（x+2）+（5x+10）=90 degrees
so 6x+12=90
x=13
5x+10=5x13+10=75 degrees
Answer:
