Answer:
a>-1/3
Step-by-step explanation:
-7a-2a<3
-9a<3
-a<3/9
a>-3/9
a>-1/3
You switch the sign because your dividing by a negative.
Answer:
now using the formula (a-b) (a2+ab+b2)=a3-b3
=>x3-63
x3-216#answer
Answer:
B) 6 tan(35°)
Step-by-step explanation:
from the right angle tan° = opposite / adjacent
therefore tan (35°) = (x) / 6
by multiplying 6 to both sides
tan (35°) * 6 = (x) / 6 * 6
therefore (x) = 6 tan (35°)
We know: The sum of measures of a tringle is equal 180°.
Therefore we have the equation:
m∠SQR + 58° + 35° = 180°
m∠SQR + 93° = 180° <em>subtract 93° from both sides</em>
m∠SQR = 87°
Angles SQR and PQR are supplementary. The sum of the measures of supplementary angles is 180°.
Therefore:
x + 87 = 180 <em>subtract 87 from both sides</em>
<h3>
x = 93</h3>
Answer:
70 degrees.
Step-by-step explanation:
Let the angle be x then:
Its supplement is 180-x.
Its complement = 90 - x.
The supplement of the complement = (180 - (90 - x) = 90 + x.
So we have the equation:
180 - x = 2(90 + x) - 60.
180 - x = 180 + 2x - 60
- x - 2x = 180 - 180 - 60
-3x = -60
x = 20 degrees
So the measure of the complement = 90 - 20 = 70 degrees.
