Answer:
B
Step-by-step explanation:
Sin 20 is the answer
Using the trigonometry rule
Sin cos tan
Sin x = opposite side (a) / hypotenuse side (c)
A/c = sin x
x= 20 ( angle formed by side c and b )
Answer:
7
Step-by-step explanation:
<u>3 </u>+ 4 = 7.
So, therefor, x = 3
Answer:
1/2 of the cup.
Step-by-step explanation:
3/4 is half of 1 1/2.
Linear pairs add up to 180 degrees.
7w - 20 + w + 100 = 180
8w + 80 = 180
8w = 100
w = 12.5
BNR = 7w - 20 = 87.5 - 20 = 67.5
RNA = w + 100 = 112.5
RNA is bigger by 112.5 - 67.5 = 45.
w = 12.5, BNR = 67.5, RNA = 112.5,
RNA is bigger by 45 degrees.
