Answer:
∠4 and ∠3
∠4 and ∠5
∠3 and ∠6
Step-by-step explanation:
A pair of angles is said to be supplementary when the 2 angles add up to give 180°.
Two right angles add up to give 180°. Also, if we have two angles on a straight line, their sum = 180°, according to the linear pair property.
Thus, since m< 3 is given as 90°, m<4 = 90°.
m<4 + m<3 = 180°.
Therefore, <4 and <3 are supplementary.
<4 and <5, <3 and <6 are both linear pairs, therefore they are also supplementary.
Answer:
4
Step-by-step explanation:
5(x + 1) -x = 17 Distribute the 5
5x + 5 - x = 17 Combine like terms
4x + 5 = 17 Subtract 5 from both sides
4x = 12 Divide both sides by 4
x = 3
Three is the smaller integer and 4 is the greater integer.
17,190 / 5,730 = 3. This means we must divide 70mg in half 3 times
70 / 2 = 35
35 / 2 = 17.5
17.5 / 2 = 8.75
There will be 8.75 mg left after 17,190 years.
Answer:
D.
Each line has the 3 dashes meaning equivalent
First of all, let’s find CB.
sin(45°) = CB : 6sqrt(2)
CB = 6
Now we can find CD
cos(60°) = x : 6
x = 3
