Answer: the equation to determine the value of n is 5n = 105
Step-by-step explanation:
The measure of angle a is n degrees. The measure of angle b is four times angle a. This means that the measure of angle b would be
b = 4n
The measure of angle c is 75 degrees. Since the sum of the interior angles of a quadrilateral is 180 degrees, then the equation to determine the value of n would be
a + b + c = 180
Therefore,
n + 4n + 75 = 180
5n = 180 - 75
5n = 105
n = 105/5
n = 21
How to find the radius of a circle with a circumference of 10 centimeters? To find the radius of a circle with a circumference of 10 centimeters, you have to do the following: Divide the circumference by π, or 3.14 for an estimation. The result is the circle's diameter, 3.18 centimeters.
Answer:
22.5^3
Step-by-step explanation:
V=length*width*height=2*2.5*4.5=22.5 m^3
Answer:
B.less than 90 degrees
Step-by-step explanation:
Obtuse angle is greater than 90°
Since the sum of all 3 angles= 180°
The sum of other 2 angles less than 180°-90°= 90°
