Answer:
To find a
sin 30=a/6in
1/2=a/6in
2a=6in
a=6in/2
a=3in
To find b
cos 30=b/6in
/3/2=b/6in
2b=/3*6in
b=2/3(two radical three)
I don't get the radical sign so I use / sign on the last 3 steps on the second
Answer:
The answer to your question is:
Step-by-step explanation:
1.-
y = 84°
5x - 61 = 84
5x = 84 + 61
5x = 145
x = 29
2.-
m∠1 + m∠6 = 180 they are supplementary angles
∠1 = 180 - 143
∠1 = 37
∠1 = ∠ 3 because are vertical angles.
3.-
m∠2 + m∠5 = 180 they are supplementary angles
∠2 + 79 = 180
∠2 = 180 - 79
∠2 = 101
m∠3 = m∠5 they are alternate angles
Answer:
1).false 2). false 3).true 4). true
Step-by-step explanation:
1).All whole numbers are integers, so s...” That's right! All whole numbers are integers, so since 0 is a whole number, 0 is also an integer.
3).. Integers include all whole numbers and their negative counter part e.g. … -4, -3, -2, -1, 0,1, 2, 3, 4,… Where a and b are both integers. is a rational number but not an integer. 4). All integers are rational number. Since we can rewrite an integer into a fractional form by diving it by 1. For example, 4=41 4 = 4 1 . But not all rational numbers are integer.
