Answer:
a < 3
n < 3
Step-by-step explanation:
We will solve each inequality one by one.
Solve first inequality :
3a - 4 < 5
add 4 both the side
3a < 9
divide 3 both the side
a < 3
Solve second inequality:
subtract 5 both the side
now multiply by -3 both the side and reverse the inequality sign
n < (-3)*(-1)
n < 3
That's the final answer. I hope it will help you.
The measure of angle 2 is
Explanation:
Given that and
are complementary angles.
Also, the measure of angle 1 is
We need to determine the measure of
Since, we know that the complementary angles add up to 90°, then the angles and
add up to 90°.
Thus, we have,
Substituting the value of in the above expression, we have,
Subtracting both sides by 76°, we get,
Simplifying, we have,
Thus, the measure of angle 2 is
