Answer:
n=4
Step-by-step explanation:
To solve combine your like terms.
You can start by adding 0.8 to both sides and subtracting 0.7n from both sides.
Next, divide both sides by 0.7 to isolate for n.

Answer: The measure of the other acute angle is 52.8°
Step-by-step explanation:
Hi, since the situation described forms a right triangle ( see attachment) , we know that the three interior angles of a right triangle add up to 180 degrees.
The value of one angle is given = 37.2°.
Since is a right angle it has also a right angle of 90°.
So we can write an equation:
x + 37.2 + 90 = 180
Where x is the measure of the other acute angle.
Solving for x:
x = 180-90-37.2
x = 52.8°
Answer:
m∠ADC = 20°
Step-by-step explanation:
A circle B has points B, C and D on the circumference.
m∠ABC = 40° [Cntral angle]
Since measure of the central angle is double of the inscribed angle by the arc
m∠ABC = 2(m∠ADC)
Here ∠ABC = Central angle
and ∠ADC = Inscribed angle
40° = 2(m∠ADC)
m∠ADC =
= 20°
Therefore, measure of angle ADC is 20°.
