Answer:
first one
2m=1 == 2+m-1+m
Step-by-step explanation:
Answer:
the numbers next to a variable is a coefficient, for instance in 2x 2 would be the coefficient.
the constants are the numbers without variables next to them, just numbers
like terms are the term that are similar like 2x and 8x or even 5 and 3
lm not exactly sure what they mean when asking for constant terms.
Yes because 84+45 is 129 and 3(28+15) is 129
It adds up to 180 degrees
The measure of Arc Q P is 96°. We also know that ∠QTP is central angle, then the measure of arc QP is 96°.
Step-by-step explanation:
<u>Step 1</u>
If QS is a circle diameter,
then m∠QTS=180°.
Let x be the measure of angle RTQ: ∠RTQ =x.
so, let ∠RTQ = x
<u />
<u>Step 2</u>
According to the question,
∠RTQ = ∠RTS - 12°
⇒ ∠RTS = x + 12°
∴ ∠QTS = ∠RTQ + ∠RTS
= x + x + 12° = 2x + 12° = 180°
⇒ 2x = 168°
⇒ x = 84°
⇒ ∠RTQ = 84°
<u></u>
<u>Step 3</u>
Now,
∵∠QTP and ∠RTS are vertical angles
∴ ∠QTP = 84° + 12° = 96°
As ∠QTP is the central angle, hence the measure of arc QP is 96°
<u></u>
<u>Step 4</u>
The Measure of arc QP = 96°
